Tom Lane	7d4d5c00f0	Arrange to recycle old XLOG log segment files as new segment files, ... rather than deleting them only to have to create more. Steady state is 2*CHECKPOINT_SEGMENTS + WAL_FILES + 1 segment files, which will simply be renamed rather than constantly deleted and recreated. To make this safe, added current XLOG file/offset number to page header of XLOG pages, so that an un-overwritten page from an old incarnation of a logfile can be reliably told from a valid page. This change means that if you try to restart postmaster in a CVS-tip database after installing the change, you'll get a complaint about bad XLOG page magic number. If you don't want to initdb, run contrib/pg_resetxlog (and be sure you shut down the old postmaster cleanly).	25 years ago

Tom Lane	ccf193f1a5	New-style vacuum neglected to update pg_class statistics about indexes ... if there were no deletions to do.	25 years ago
Tom Lane	75586cb584	Disallow non-cachable functions in functional indexes and in index ... predicates. Per suggestion from Hiroshi.	25 years ago
Tom Lane	84a3634411	Avoid assuming that pg_index table entries have unique OIDs, or even ... that they have OIDs at all (the primary key for this table is indexrelid, not OID). Simplify overly complex query to get name of primary key.	25 years ago
Tom Lane	ed5c4e4a14	Improve documentation about reasoning behind the order of operations ... 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.	25 years ago

Tom Lane	40db52af34	Do not push down quals into subqueries that have LIMIT/OFFSET clauses, ... since the added qual could change the set of rows that get past the LIMIT. Per discussion on pgsql-sql 7/15/01.	25 years ago

Tom Lane	f31dc0ada7	Partial indexes work again, courtesy of Martijn van Oosterhout. ... 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.	25 years ago

Tom Lane	c8076f09d2	Restructure index AM interface for index building and index tuple deletion, ... 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.	25 years ago
Tom Lane	997439f59e	Add ORDER BY to a couple of test queries whose output ordering is not ... as predictable as it used to be, due to recycling of free space with new VACUUM.	25 years ago

Bruce Momjian	b08e86d557	The attached patch fixes problems with the JDBC driver handling long ... 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	25 years ago
