* sum() on int2 and int4 columns now uses an int8, not numeric, accumulatorTom Lane2001-08-14
| | | | | | | | | | | | | | | | | | | | for speed reasons; its result type also changes to int8. avg() on these datatypes now accumulates the running sum in int8 for speed; but we still deliver the final result as numeric, so that fractional accuracy is preserved. count() now counts and returns in int8, not int4. I am a little nervous about this possibly breaking users' code, but there didn't seem to be a strong sentiment for avoiding the problem. If we get complaints during beta, we can change count back to int4 and add a "count8" aggregate. For that matter, users can do it for themselves with a simple CREATE AGGREGATE command; the int4inc function is still present, so no C hacking is needed. Also added max() and min() aggregates for OID that do proper unsigned comparison, instead of piggybacking on int4 aggregates. initdb forced.
* Fix brokenness of nested EXCEPT/INTERSECT queries. prepunion was beingTom Lane2001-08-14

* Make LANCOMPILER clause in CREATE LANGUAGE optional. Allow "identifier"Peter Eisentraut2001-08-13
| | | | | | | | | | | | syntax for language names (instead of 'string'). createlang now handles the case where a second language uses the same call handler as an already installed language (e.g., plperl/plperlu). droplang now handles the reverse case, i.e., dropping a language where the call handler is still used by another language. Moreover, droplang can now be used to drop any user-defined language, not just the supplied ones.

| | | | | | | | | | | | default, but OIDS are removed from many system catalogs that don't need them. Some interesting side effects: TOAST pointers are 20 bytes not 32 now; pg_description has a three-column key instead of one. Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey has some usefulness; pg_dump dumps comments on indexes, rules, and triggers in a valid order. initdb forced.

| | | | | | | | | | | | | | (as proposed in http://fts.postgresql.org/db/mw/msg.html?mid=1028327) 2. support for 'pass-by-value' arguments - to test this we used special opclass for int4 with values in range [0-2^15] More testing will be done after resolving problem with index_formtuple and implementation of B-tree using GiST 3. small patch to contrib modules (seg,cube,rtree_gist,intarray) - mark functions as 'isstrict' where needed.

| | | | | | | | | | | | cvs. The Debian bug report says, "The upstream source makes use of NOFILE unconditionalized. As the Hurd doesn't have an arbitrary limit on the number of open files, this is not defined. But _SC_OPEN_MAX works fine and returns 1024 (applications can increase this as they want), so I suggest the below diff. Please forward this upstream, too." Oliver Elphick

* Attached is a patch that does the following:Bruce Momjian2001-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) improves performance of commit/rollback by reducing number of round trips to the server 2) uses 7.1 functionality for setting the transaction isolation level 3) backs out a patch from 11 days ago because that code failed to compile under jdk1.1 Details: 1) The old code was doing the following for each commit: commit begin set transaction isolation level xxx thus a call to commit was performing three round trips to the database. The new code does this in one round trip as: commit; begin; set transaction isolation level xxx In a simple test program that performs 1000 transactions (where each transaction does one simple select inside that transaction) has the following before and after timings: Client and Server on same machine old new --- --- 1.877sec 1.405sec 25.1% improvement Client and Server on different machines old new --- --- 4.184sec 2.927sec 34.3% improvement (all timings are an average of four different runs) 2) The driver was using 'set transaction isolation level xxx' at the begining of each transaction, instead of using the new 7.1 syntax of 'set session characteristics as transaction isolation level xxx' which only needs to be done once instead of for each transaction. This is done conditionally (i.e. if server is 7.0 or older do the old behaviour, else do the new behaviour) to not break backward compatibility. This also required the movement of some code to check/test database version numbers from the DatabaseMetaData object to the Connection object. 3) Finally while testing, I discovered that the code that was checked in 11 days ago actually didn't compile. The code in the patch for Connection.setCatalog() used Properties.setProperty() which only exists in JDK1.2 or higher. Thus compiling the JDBC1 driver failed as this method doesn't exist. Thus I backed out that patch. Barry Lind
