* pg_class has a relnamespace column. You can create and access tablesTom Lane2002-03-26
| | | | | | in schemas other than the system namespace; however, there's no search path yet, and not all operations work yet on tables outside the system namespace.
* Change made to elog:Bruce Momjian2002-03-06
| | | | | | | | | | | | | | | | | | | o Change all current CVS messages of NOTICE to WARNING. We were going to do this just before 7.3 beta but it has to be done now, as you will see below. o Change current INFO messages that should be controlled by client_min_messages to NOTICE. o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc. to always go to the client. o Remove INFO from the client_min_messages options and add NOTICE. Seems we do need three non-ERROR elog levels to handle the various behaviors we need for these messages. Regression passed.
* Commit to match discussed elog() changes. Only update is that LOG isBruce Momjian2002-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | now just below FATAL in server_min_messages. Added more text to highlight ordering difference between it and client_min_messages. --------------------------------------------------------------------------- REALLYFATAL => PANIC STOP => PANIC New INFO level the prints to client by default New LOG level the prints to server log by default Cause VACUUM information to print only to the client NOTICE => INFO where purely information messages are sent DEBUG => LOG for purely server status messages DEBUG removed, kept as backward compatible DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added DebugLvl removed in favor of new DEBUG[1-5] symbols New server_min_messages GUC parameter with values: DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC New client_min_messages GUC parameter with values: DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC Server startup now logged with LOG instead of DEBUG Remove debug_level GUC parameter elog() numbers now start at 10 Add test to print error message if older elog() values are passed to elog() Bootstrap mode now has a -d that requires an argument, like postmaster
* User and database-specific session defaults for run-time configurationPeter Eisentraut2002-03-01
| | | | variables. New commands ALTER DATABASE ... SET and ALTER USER ... SET.
* New pgindent run with fixes suggested by Tom. Patch manually reviewed,Bruce Momjian2001-11-05
| | | | initdb/regression tests pass.
* Merge three existing ways of signaling postmaster from child processes,Tom Lane2001-11-04
| | | | | | | | | | | so that only one signal number is used not three. Flags in shared memory tell the reason(s) for the current signal. This method is extensible to handle more signal reasons without chewing up even more signal numbers, but the immediate reason is to keep pg_pwd reloads separate from SIGHUP processing in the postmaster. Also clean up some problems in the postmaster with delayed response to checkpoint status changes --- basically, it wouldn't schedule a checkpoint if it wasn't getting connection requests on a regular basis.
* Fix pg_pwd caching mechanism, which was broken by changes to forkTom Lane2001-11-02
| | | | | | | postmaster children before client auth step. Postmaster now rereads pg_pwd on receipt of SIGHUP, the same way that pg_hba.conf is handled. No cycles need be expended to validate password cache validity during connection startup.
* Reject tabs and linefeeds in usernames and passwords that are beingTom Lane2001-11-01
| | | | | | stored in pg_pwd, to guard against failures of the sort observed by Tom Yackel. Note: in the case of encrypted passwords this is no restriction, since the string we are interested in is the MD5 hash.
* Another pgindent run. Fixes enum indenting, and improves #endifBruce Momjian2001-10-28
| | | | spacing. Also adds space for one-line comments.
* pgindent run on all C files. Java run to follow. initdb/regressionBruce Momjian2001-10-25
| | | | tests pass.
* Replace useless strcasecmp's by strcmp's.Peter Eisentraut2001-09-19
|
* Make the world somewhat safe for (not from) DELETE FROM pg_shadow;Peter Eisentraut2001-09-08
| | | | | | | | | | | | | | | | | | | | | Assign the fixed user id 1 to the user created by initdb. A stand-alone backend will always set the user id to 1. (Consequently, the name of that user is no longer important.) In stand-alone mode, the user id 1 will have implicit superuser status, to allow repairs even if there are no users defined. Print a warning message when starting in stand-alone mode when no users are defined. Disallow dropping the current user and session user. Granting/revoking superuser status also grants/revokes usecatupd. (Previously, it would never grant it back. This could lead to "deadlocks".) CREATE USER and CREATE GROUP will start allocating user ids at 100 (unless explicitly specified), to prevent accidental creation of a superuser (plus some room for future extensions).
* Add 4-byte MD5 salt.Bruce Momjian2001-08-17
|
* Move md5.h contents to crypt.h.Bruce Momjian2001-08-15
|
* Use MD5 for wire protocol encryption for >= 7.2 client/server.Bruce Momjian2001-08-15
| | | | | | | Allow pg_shadow to be MD5 encrypted. Add ENCRYPTED/UNENCRYPTED option to CREATE/ALTER user. Add password_encryption postgresql.conf option. Update wire protocol version to 2.1.
* Remove grammar restrictions on order of optional clauses in CREATE GROUP.Tom Lane2001-07-12
| | | | From Vince Vielhaber.
* Changes from Vince Vielhaber to allow the optional clauses of CREATETom Lane2001-07-10
| | | | | | | | USER and ALTER USER to appear in any order, not only the fixed order they used to be required to appear in. Also, some changes from Tom Lane to create a FULL option for VACUUM; it doesn't do anything yet, but I needed to change many of the same files to make that happen, so now seemed like a good time.
* has_table_privilege functions from Joe Conway (with some kibitzing fromTom Lane2001-06-14
| | | | | | Tom Lane). For the moment, only the OID/name variants are provided. I didn't force initdb, but the additions to the 'privileges' regress test won't pass until you do one.
* Clean up various to-do items associated with system indexes:Tom Lane2001-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pg_database now has unique indexes on oid and on datname. pg_shadow now has unique indexes on usename and on usesysid. pg_am now has unique index on oid. pg_opclass now has unique index on oid. pg_amproc now has unique index on amid+amopclaid+amprocnum. Remove pg_rewrite's unnecessary index on oid, delete unused RULEOID syscache. Remove index on pg_listener and associated syscache for performance reasons (caching rows that are certain to change before you need 'em again is rather pointless). Change pg_attrdef's nonunique index on adrelid into a unique index on adrelid+adnum. Fix various incorrect settings of pg_class.relisshared, make that the primary reference point for whether a relation is shared or not. IsSharedSystemRelationName() is now only consulted to initialize relisshared during initial creation of tables and indexes. In theory we might now support shared user relations, though it's not clear how one would get entries for them into pg_class &etc of multiple databases. Fix recently reported bug that pg_attribute rows created for an index all have the same OID. (Proof that non-unique OID doesn't matter unless it's actually used to do lookups ;-)) There's no need to treat pg_trigger, pg_attrdef, pg_relcheck as bootstrap relations. Convert them into plain system catalogs without hardwired entries in pg_class and friends. Unify global.bki and template1.bki into a single init script postgres.bki, since the alleged distinction between them was misleading and pointless. Not to mention that it didn't work for setting up indexes on shared system relations. Rationalize locking of pg_shadow, pg_group, pg_attrdef (no need to use AccessExclusiveLock where ExclusiveLock or even RowExclusiveLock will do). Also, hold locks until transaction commit where necessary.
* Remove dashes in comments that don't need them, rewrap with pgindent.Bruce Momjian2001-03-22

* pgindent run. Make it all clean.Bruce Momjian2001-03-22

* Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.Bruce Momjian2001-01-24
|
* Fix all the places that called heap_update() and heap_delete() withoutTom Lane2001-01-23
| | | | | | | | | | | bothering to check the return value --- which meant that in case the update or delete failed because of a concurrent update, you'd not find out about it, except by observing later that the transaction produced the wrong outcome. There are now subroutines simple_heap_update and simple_heap_delete that should be used anyplace that you're not prepared to do the full nine yards of coping with concurrent updates. In practice, that seems to mean absolutely everywhere but the executor, because *noplace* else was checking.
* Change lcons(x, NIL) to makeList(x) where appropriate.Bruce Momjian2001-01-17
|
* Change SearchSysCache coding conventions so that a reference count isTom Lane2000-11-16
| | | | | | | maintained for each cache entry. A cache entry will not be freed until the matching ReleaseSysCache call has been executed. This eliminates worries about cache entries getting dropped while still in use. See my posting to pg-hackers of even date for more info.
* Fix missing CommandCounterIncrement in DROP USER.Tom Lane2000-10-19
|
* Implement differentiation between CURRENT_USER and SESSION_USER as per SQL.Peter Eisentraut2000-09-19
| | | | | | There is still no effective difference but it will kick in once setuid functions exist (not included here). Make old getpgusername() alias for current_user.
* Clean up callers of AllocateFile and BasicOpenFile to ensure thatTom Lane2000-08-27
| | | | | a reasonable error message (including the kernel errno message) is reported on any file open failure.
* More functions updated to new fmgr style --- money, name, tid datatypes.Tom Lane2000-08-03
| | | | | We're reaching the mopup stage here (good thing too, this is getting tedious).
* Missed some array updates ...Tom Lane2000-07-22
|
* Revise aggregate functions per earlier discussions in pghackers.Tom Lane2000-07-17
| | | | | | | | | | | There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...
* Update textin() and textout() to new fmgr style. This is just phaseTom Lane2000-07-05
| | | | | one of updating the whole text datatype, but there are so dang many calls of these two routines that it seems worth a separate commit.
* First phase of memory management rewrite (see backend/utils/mmgr/READMETom Lane2000-06-28
| | | | | | | | | | | | | for details). It doesn't really do that much yet, since there are no short-term memory contexts in the executor, but the infrastructure is in place and long-term contexts are handled reasonably. A few long- standing bugs have been fixed, such as 'VACUUM; anything' in a single query string crashing. Also, out-of-memory is now considered a recoverable ERROR, not FATAL. Eliminate a large amount of crufty, now-dead code in and around memory management. Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and backend startup.
* Relaxed pickiness about user and group commands in transaction blocks.Peter Eisentraut2000-06-25

* Back out pg_shadow changes to allow create table and locking permissions.Bruce Momjian2000-06-12

* I have large database and with this DB work more users and I very needBruce Momjian2000-06-09
| | | | | | | | | | | | | | | | | | | | | | | | more restriction for fretful users. The current PG allow define only NO-CREATE-DB and NO-CREATE-USER restriction, but for some users I need NO-CREATE-TABLE and NO-LOCK-TABLE. This patch add to current code NOCREATETABLE and NOLOCKTABLE feature: CREATE USER username [ WITH [ SYSID uid ] [ PASSWORD 'password' ] ] [ CREATEDB | NOCREATEDB ] [ CREATEUSER | NOCREATEUSER ] -> [ CREATETABLE | NOCREATETABLE ] [ LOCKTABLE | NOLOCKTABLE ] ...etc. If CREATETABLE or LOCKTABLE is not specific in CREATE USER command, as default is set CREATETABLE or LOCKTABLE (true). A user with NOCREATETABLE restriction can't call CREATE TABLE or SELECT INTO commands, only create temp table is allow for him. Karel
* Another round of updates for new fmgr, mostly in the datetime code.Tom Lane2000-06-09

* Create an fd.c entry point that is just like plain open(2) except thatTom Lane2000-06-02
| | | | | | | | | | it will close VFDs if necessary to surmount ENFILE or EMFILE failures. Make use of this in md.c, xlog.c, and user.c routines that were formerly vulnerable to these failures. In particular, this should handle failures of mdblindwrt() that have been observed under heavy load conditions. (By golly, every other process on the system may crash after Postgres eats up all the kernel FDs, but Postgres will keep going!)
* Remove unused include files. Do not touch /port or includes used by defines.Bruce Momjian2000-05-30

* Second round of fmgr changes: triggers are now invoked in new style,Tom Lane2000-05-29
| | | | CurrentTriggerData is history.
* First round of changes for new fmgr interface. fmgr itself and theTom Lane2000-05-28
| | | | | | | key call sites are changed, but most called functions are still oldstyle. An exception is that the PL managers are updated (so, for example, NULL handling now behaves as expected in plperl and plpgsql functions). NOTE initdb is forced due to added column in pg_proc.

* * User management commands no longer user pg_exec_query_dest -> more robustPeter Eisentraut2000-01-14
| | | | | | | | | | | | * Let unprivileged users change their own passwords. * The password is now an Sconst in the parser, which better reflects its text datatype and also forces users to quote them. * If your password is NULL you won't be written to the password file, meaning you can't connect until you have a password set up (if you use password authentication). * When you drop a user that owns a database you get an error. The database is not gone.
