* Replace "amgetmulti" AM functions with "amgetbitmap", in which the wholeTom Lane2008-04-10
| | | | | | | | | | | | | | | | | | indexscan always occurs in one call, and the results are returned in a TIDBitmap instead of a limited-size array of TIDs. This should improve speed a little by reducing AM entry/exit overhead, and it is necessary infrastructure if we are ever to support bitmap indexes. In an only slightly related change, add support for TIDBitmaps to preserve (somewhat lossily) the knowledge that particular TIDs reported by an index need to have their quals rechecked when the heap is visited. This facility is not really used yet; we'll need to extend the forced-recheck feature to plain indexscans before it's useful, and that hasn't been coded yet. The intent is to use it to clean up 8.3's horrid @@@ kluge for text search with weighted queries. There might be other uses in future, but that one alone is sufficient reason. Heikki Linnakangas, with some adjustments by me.

* Implement a few changes to how shared libraries and dynamically loadablePeter Eisentraut2008-04-07
| | | | | | | | | | | | | | | modules are built. Foremost, it creates a solid distinction between these two types of targets based on what had already been implemented and duplicated in ad hoc ways before. Specifically, - Dynamically loadable modules no longer get a soname. The numbers previously set in the makefiles were dummy numbers anyway, and the presence of a soname upset a few packaging tools, so it is nicer not to have one. - The cumbersome detour taken on installation (build a libfoo.so.0.0.0 and then override the rule to install foo.so instead) is removed. - Lots of duplicated code simplified.

* Improve hash_any() to use word-wide fetches when hashing suitably alignedTom Lane2008-04-06
| | | | | | | | | | | | | data. This makes for a significant speedup at the cost that the results now vary between little-endian and big-endian machines; which forces us to add explicit ORDER BYs in a couple of regression tests to preserve machine-independent comparison results. Also, force initdb by bumping catversion, since the contents of hash indexes will change (at least on big-endian machines). Kenneth Marshall and Tom Lane, based on work from Bob Jenkins. This commit does not adopt Bob's new faster mix() algorithm, however, since we still need to convince ourselves that that doesn't degrade the quality of the hashing.

* Defend against JOINs having more than 32K columns altogether. We cannotTom Lane2008-04-05
| | | | | | | | | | | | currently support this because we must be able to build Vars referencing join columns, and varattno is only 16 bits wide. Perhaps this should be improved in future, but considering that it never came up before, I'm not sure the problem is worth much effort. Per bug #4070 from Marcello Ceschia. The problem seems largely academic in 8.0 and 7.4, because they have (different) O(N^2) performance issues with such wide joins, but back-patch all the way anyway.
* Have pg_stop_backup() wait for all archive files to be sent, rather thanBruce Momjian2008-04-05

* Re-implement division for numeric values using the traditional "schoolbook"Tom Lane2008-04-04
| | | | | | | | | | | | algorithm. This is a good deal slower than our old roundoff-error-prone code for long inputs, so we keep the old code for use in the transcendental functions, where everything is approximate anyway. Also create a user-accessible function div(numeric, numeric) to provide access to the exact result of trunc(x/y) --- since the regular numeric / operator will round off its result, simply computing that expression in SQL doesn't reliably give the desired answer. This fixes bug #3387 and various related corner cases, and improves the usefulness of PG for high-precision integer arithmetic.

* Teach ANALYZE to distinguish dead and in-doubt tuples, which it formerlyTom Lane2008-04-03
| | | | | | | | | | | | | | | classed all as "dead"; also get it to count DEAD item pointers as dead rows, instead of ignoring them as before. Also improve matters so that tuples previously inserted or deleted by our own transaction are handled nicely: the stats collector's live-tuple and dead-tuple counts will end up correct after our transaction ends, regardless of whether we end in commit or abort. While there's more work that could be done to improve the counting of in-doubt tuples in both VACUUM and ANALYZE, this commit is enough to alleviate some known bad behaviors in 8.3; and the other stuff that's been discussed seems like research projects anyway.

* Revert my bad decision of about a year ago to make PortalDefineQueryTom Lane2008-04-02
| | | | | | | | | | | | | | responsible for copying the query string into the new Portal. Such copying is unnecessary in the common code path through exec_simple_query, and in this case it can be enormously expensive because the string might contain a large number of individual commands; we were copying the entire, long string for each command, resulting in O(N^2) behavior for N commands. (This is the cause of bug #4079.) A second problem with it is that PortalDefineQuery really can't risk error, because if it elog's before having set up the Portal, we will leak the plancache refcount that the caller is trying to hand off to the portal. So go back to the design in which the caller is responsible for making sure everything is copied into the portal if necessary.
