* Improve documentation about reasoning behind the order of operationsTom Lane2001-07-16
| | | | | | | | in GetSnapshotData, GetNewTransactionId, CommitTransaction, AbortTransaction, etc. Correct race condition in transaction status testing in HeapTupleSatisfiesVacuum --- this wasn't important for old VACUUM with exclusive lock on its table, but it sure is important now. All per pghackers discussion 7/11/01 and 7/12/01.

* Do not push down quals into subqueries that have LIMIT/OFFSET clauses,Tom Lane2001-07-16

* Partial indexes work again, courtesy of Martijn van Oosterhout.Tom Lane2001-07-16
| | | | | | Note: I didn't force an initdb, figuring that one today was enough. However, there is a new function in pg_proc.h, and pg_dump won't be able to dump partial indexes until you add that function.

* Restructure index AM interface for index building and index tuple deletion,Tom Lane2001-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | per previous discussion on pghackers. Most of the duplicate code in different AMs' ambuild routines has been moved out to a common routine in index.c; this means that all index types now do the right things about inserting recently-dead tuples, etc. (I also removed support for EXTEND INDEX in the ambuild routines, since that's about to go away anyway, and it cluttered the code a lot.) The retail indextuple deletion routines have been replaced by a "bulk delete" routine in which the indexscan is inside the access method. I haven't pushed this change as far as it should go yet, but it should allow considerable simplification of the internal bookkeeping for deletions. Also, add flag columns to pg_am to eliminate various hardcoded tests on AM OIDs, and remove unused pg_am columns. Fix rtree and gist index types to not attempt to store NULLs; before this, gist usually crashed, while rtree managed not to crash but computed wacko bounding boxes for NULL entries (which might have had something to do with the performance problems we've heard about occasionally). Add AtEOXact routines to hash, rtree, and gist, all of which have static state that needs to be reset after an error. We discovered this need long ago for btree, but missed the other guys. Oh, one more thing: concurrent VACUUM is now the default.
* Add ORDER BY to a couple of test queries whose output ordering is notTom Lane2001-07-15

* The attached patch fixes problems with the JDBC driver handling longBruce Momjian2001-07-15
| | | | | | | | | | | | | | | | | | | | | | | | null terminated strings. The FE/BE protocol sends in some cases null terminated strings to the client. The docs for the FE/BE protocol state that there is no limit on the size of a null terminated string sent to the client and a client should be coded using an expanding buffer to deal with large strings. The old code did not do this and gave an error if a null terminated string was greater than either 4 or 8K. It appears that with the advent of TOAST very long SQL statements are becoming more common, and apparently some error messages from the backend include the SQL statement thus easily exceeding the 8K limit in the old code. In fixing I also cleaned up some calls in the JDBC fastpath code that were not doing character set conversion under multibyte, and removed some methods that were no longer needed. I also removed a potential threading problem with a shared variable that was being used in Connection.java. Thanks to Steve Wampler for discovering the problem and sending the initial diffs that were the basis of this patch. thanks, --Barry
* Initial implementation of concurrent VACUUM. Ifdef'd out for the moment,Tom Lane2001-07-13

* Instead of believing SOMAXCONN from the system header files (which isTom Lane2001-07-11

* Remove direct calls of index_insert(), instead use ExecInsertIndexTuples().Tom Lane2001-07-11
| | | | | | | This makes VACUUM work properly with partial indexes, and avoids memory leakage with functional indexes. Also, suppress complaint about fewer index tuples than heap tuples when the index is a partial index. From Martijn van Oosterhout.
