* Fix for systems that don't have INET_ADDRSTRLEN.Peter Eisentraut2003-01-06
|
* Enable IPv6 connections to the server, and add pg_hba.conf IPv6 entriesBruce Momjian2003-01-06
| | | | | | | if the OS supports it. Code will still compile on non-IPv6-aware machines (feature added by Bruce). Nigel Kukard
* ALTER DOMAIN OWNER, from Rod Taylor.Tom Lane2003-01-06
|
* Fix inherited UPDATE for cases where child column numbering doesn'tTom Lane2003-01-05
| | | | | | match parent table. This used to work, but was broken in 7.3 by rearrangement of code that handles targetlist sorting. Add a regression test to catch future breakage.
* Partial code review for ALTER DOMAIN patch. Incorporates Rod Taylor'sTom Lane2003-01-04
| | | | | | | | patches of 9-Dec (permissions fix) and 13-Dec (performance) as well as a partial fix for locking issues: concurrent DROP COLUMN should not create trouble anymore. But concurrent DROP TABLE is still a risk, and there is no protection at all against creating a column of a domain while we are altering the domain.
* Enforces NOT NULL constraints to be applied against new PRIMARY KEYTom Lane2003-01-02
| | | | | | | | | columns in DefineIndex. So, ALTER TABLE ... PRIMARY KEY will now automatically add the NOT NULL constraint. It appeared the alter_table regression test wanted this to occur, as after the change the regression test better matched in inline 'fails'/'succeeds' comments. Rod Taylor
* fastpath code neglected to check whether user has privileges to call theTom Lane2003-01-01
| | | | | target function. Also, move SetQuerySnapshot() call to avoid assert failure when a fastpath call is attempted in an aborted transaction.
* Adjust Tcl-related code to compile cleanly with Tcl 8.4 (add const modifiers asTom Lane2002-12-30
| | | | needed). Some desultory const-ification of SPI interface to support this.
* Code review for transaction-safe-TRUNCATE patch: minor cleanups.Tom Lane2002-12-30
|
* Code review for CLUSTER ALL patch. Fix bogus locking, incorrect transactionTom Lane2002-12-30
| | | | stop/start nesting, other infelicities.
* Cause FETCH 1 to return the current cursor row, or zero if atBruce Momjian2002-12-30
| | | | | | | | | | | | beginning/end of cursor. Have MOVE return 0/1 depending on cursor position. Matches SQL spec. Pass cursor counter from parser as a long rather than int. Doc updates.
* Better solution to integer overflow problem in hash batch-numberTom Lane2002-12-30
| | | | | | | computation: reduce the bucket number mod nbatch. This changes the association between original bucket numbers and batches, but that doesn't matter. Minor other cleanups in hashjoin code to help centralize decisions.
* Point does not return a center of lseg.Tom Lane2002-12-30
| | | | Kenji Sugita
* Adjust hash table sizing algorithm to avoid integer overflow inTom Lane2002-12-29
| | | | | ExecHashJoinGetBatch(). Fixes core dump on large hash joins, as in example from Rae Stiening.
* Deliver better error message when a relation name is used in an expression.Tom Lane2002-12-27
| | | | Per report from Ian Barwick.
* Trivial patch to increase max_fsm_pages as per earlier discussion.Bruce Momjian2002-12-27
| | | | Philip Warner
* Clamp the output of estimate_hash_bucketsize() to a sane range;Tom Lane2002-12-26
| | | | per example from Bruno Wolff in which it produced a silly result.
* Don't try to free executor state of an InitPlan early --- this breaksTom Lane2002-12-26
| | | | EXPLAIN ANALYZE. (Premature optimization is the root of all evil?)
* Update SSL error message for improper permissions. Backpatch to 7.3.X.Bruce Momjian2002-12-23
|
* Cause planner to include costs of InitPlans in startup cost of parentTom Lane2002-12-19
| | | | plan node. Not sure why this oversight has persisted so long ...
* From the SSL_CTX_new man page:PostgreSQL Daemon2002-12-18
| | | | | | | | | | | | | "SSLv23_method(void), SSLv23_server_method(void), SSLv23_client_method(void) A TLS/SSL connection established with these methods will understand the SSLv2, SSLv3, and TLSv1 protocol. A client will send out SSLv2 client hello messages and will indicate that it also understands SSLv3 and TLSv1. A server will understand SSLv2, SSLv3, and TLSv1 client hello messages. This is the best choice when compatibility is a concern." This will maintain backwards compatibility for those us that don't use TLS connections ...
* Update EvalPlanQual() to work with new executor memory management method.Tom Lane2002-12-18
| | | | It doesn't leak memory anymore ...
* Prevent core dump when ExecMarkPos is called before any tuples have beenTom Lane2002-12-18
| | | | | retrieved. This cannot happen in ordinary execution, but it can happen under EvalPlanQual().
* Skip unnecessary plan-copying now that plan trees are read-only in theTom Lane2002-12-17
| | | | executor.
* To suppress memory leakage in long-lived Lists, lremove() should pfreeTom Lane2002-12-17
| | | | | the cons cell it's deleting from the list. Do this, and fix a few callers that were bogusly assuming it wouldn't free the cons cell.
* Fix GEQO to work again in CVS tip, by being more careful about memoryTom Lane2002-12-16
| | | | | | | | | | | allocation in best_inner_indexscan(). While at it, simplify GEQO's interface to the main planner --- make_join_rel() offers exactly the API it really wants, whereas calling make_rels_by_clause_joins() and make_rels_by_clauseless_joins() required jumping through hoops. Rewrite gimme_tree for clarity (sometimes iteration is much better than recursion), and approximately halve GEQO's runtime by recognizing that tours of the forms (a,b,c,d,...) and (b,a,c,d,...) are equivalent because of symmetry in make_join_rel().
* Fix ALTER TABLE ADD COLUMN to disallow the same column types that areTom Lane2002-12-16
| | | | | | | | disallowed by CREATE TABLE (eg, pseudo-types); also disallow these types from being introduced by the range-function syntax. While at it, allow CREATE TABLE to create zero-column tables, per recent pghackers discussion. I am back-patching this into 7.3 since failure to disallow pseudo-types is arguably a security hole.
* Code review for palloc0 patch --- avoid dangerous and unnecessaryTom Lane2002-12-16
| | | | | | | | practice of evaluating MemSet's arguments multiple times, except for the special case of newNode(), where we can assume the argument is a constant sizeof() operator. Also, add GetMemoryChunkContext() to mcxt.c's API, in preparation for fixing recent GEQO breakage.
* Tweak default memory context allocation policy so that a context is notTom Lane2002-12-15
| | | | | | | | | given any malloc block until something is first allocated in it; but thereafter, MemoryContextReset won't release that first malloc block. This preserves the quick-reset property of the original policy, without forcing 8K to be allocated to every context whether any of it is ever used or not. Also, remove some more no-longer-needed explicit freeing during ExecEndPlan.
* Revise executor APIs so that all per-query state structure is built inTom Lane2002-12-15
| | | | | | a per-query memory context created by CreateExecutorState --- and destroyed by FreeExecutorState. This provides a final solution to the longstanding problem of memory leaked by various ExecEndNode calls.
* The actual segfault was caused by a double pfree(), but ISTM thatBruce Momjian2002-12-14
| | | | | | | | failing to find pg_hba.conf should be a fatal error anyway, so I increased the priority of the elog() from LOG to FATAL and refactored the code a little bit. Neil Conway
* Ok, I think I've gotten this figured out now. I saw this comment inBruce Momjian2002-12-14
| | | | | | | pqcomm.c, switched the ERROR logs to COMMERROR logs and it all works. I've attached a patch to be-secure.c that fixes all my problems. Nathan Mueller
* Initial version of the SQL information schemaPeter Eisentraut2002-12-14

* Clean up plantree representation of SubPlan-s --- SubLink does not appearTom Lane2002-12-14
| | | | | | | | in the planned representation of a subplan at all any more, only SubPlan. This means subselect.c doesn't scribble on its input anymore, which seems like a good thing; and there are no longer three different possible interpretations of a SubLink. Simplify node naming and improve comments in primnodes.h. No change to stored rules, though.
* Phase 3 of read-only-plans project: ExecInitExpr now builds expressionTom Lane2002-12-13
| | | | | | | execution state trees, and ExecEvalExpr takes an expression state tree not an expression plan tree. The plan tree is now read-only as far as the executor is concerned. Next step is to begin actually exploiting this property.
* Adjust costsize calculations to avoid introducing unnecessary roundoffTom Lane2002-12-13
| | | | | error. This seems to explain the differing choice of plan that's been causing geometry regress test to fail for the last few days.
* Remove strerror output for openssl SYSCALL error check.Bruce Momjian2002-12-13
|
* Check SSL_get_error() value SSL_ERROR_SYSCALL to see if SSL_read()Bruce Momjian2002-12-12
| | | | | | returned -1, per SSL_get_error() documentation. Nathan Mueller
* TODO marked as done:Bruce Momjian2002-12-12
| | | | | | | | | | | | | | | | | | | | | * Add schema, cast, and conversion backslash commands to psql I had to create a new publically available function, pg_conversion_is_visible, as it seemed to be missing from the catalogs. This required me to do no small amount of hacking around in namespace.c I have updated the \? help and sgml docs. \dc - list conversions [PATTERN] \dC - list casts \dn list schemas I didn't support patterns with casts as there's nothing obvious to match against. Catalog version incremented --- initdb required. Christopher Kings-Lynne
* Preliminary code review for domain CHECK constraints patch: add documentation,Tom Lane2002-12-12
| | | | | | | | make VALUE a non-reserved word again, use less invasive method of passing ConstraintTestValue into transformExpr, fix problems with nested constraint testing, do correct thing with NULL result from a constraint expression, remove memory leak. Domain checks still need much more work if we are going to allow ALTER DOMAIN, however.
* Guard against overrunning CTZName buffer when TZ is bogus.Tom Lane2002-12-12
|
* Phase 2 of read-only-plans project: restructure expression-tree nodesTom Lane2002-12-12
| | | | | | | | | so that all executable expression nodes inherit from a common supertype Expr. This is somewhat of an exercise in code purity rather than any real functional advance, but getting rid of the extra Oper or Func node formerly used in each operator or function call should provide at least a little space and speed improvement. initdb forced by changes in stored-rules representation.
* Fix line count error reporting in config files, like pg_hba.conf, perBruce Momjian2002-12-11
| | | | | | report from Oliver Elphick. Backpatch to 7.3.
* Some quick fixes for ALTER DOMAIN patch. It still needs a lot of work,Tom Lane2002-12-09
| | | | but at least it doesn't generate gcc warnings.
* Fix Latin9/Unicode conversion by selecting the right table.Peter Eisentraut2002-12-09

* Explain's code for showing quals of SubqueryScan nodes has been brokenTom Lane2002-12-06
| | | | all along; not noticed till now. It's a scan not an upper qual ...
* Attached are two small patches to expose md5 as a user function -- includingBruce Momjian2002-12-06
| | | | | | | | documentation and regression test mods. It seemed small and unobtrusive enough to not require a specific proposal on the hackers list -- but if not, let me know and I'll make a pitch. Otherwise, if there are no objections please apply. Joe Conway
