* My recent fix for semijoin planning didn't actually work for a semijoin with aTom Lane2008-11-28
| | | | | | RHS that can't be unique-ified --- join_is_legal has to check that before deciding to build a join, else we'll have an unimplementable joinrel. Per report from Greg Stark.

* Reduce risk of accidentally running temp-install regression tests againstPeter Eisentraut2008-11-28
| | | | | | | | | a mismatching installation. Pick a default port number calculated from the version number, and try a few times with other numbers if that one doesn't work. Check if we can connect to the port before starting our own postmaster, to detect some other server already running there. To simplify the code, drop --temp-port option and use --port for both temp-install and pre-installed case.

* Adjust the behavior of the PQExpBuffer code to make it have well-definedTom Lane2008-11-26
| | | | | | | | | results (ie, an empty "broken" buffer) if memory overrun occurs anywhere along the way to filling the buffer. The previous coding would just silently discard portions of the intended buffer contents, as exhibited in trouble report from Sam Mason. Also, tweak psql's main loop to correctly detect and report such overruns. There's probably much more that should be done in this line, but this is a start.
* Use ResourceOwners in the snapshot manager, instead of attempting to track themAlvaro Herrera2008-11-25
| | | | | | | | by hand. As an added bonus, the new code is smaller and more understandable, and the ugly loops are gone. This had been discussed all along but never implemented. It became clear that it really needed to be fixed after a bug report by Pavan Deolasee.
* Remove PGINTERVALSTYLE from the set of special environment variables forTom Lane2008-11-25
| | | | | | | | | libpq. As noted by Peter, adding this variable created a risk of unexpected connection failures when talking to older server versions, and since it doesn't do anything you can't do with PGOPTIONS, it doesn't seem really necessary. Removing it does occasion a few extra lines in pg_regress.c, but saving a getenv() call per libpq connection attempt is perhaps worth that anyway.
* Omit src/port/pipe.c on non-Windows platforms. It's useless and drawsTom Lane2008-11-25

* If pg_ctl stop fails, print an error message and exit (instead of going outPeter Eisentraut2008-11-25
| | | | | of our way to ignore the exit status). If this ever really happens, worst case you will not see the "score" at the bottom of the test run.
* Disable FNM_CASEFOLD. Need a proper solution later, but just commentMagnus Hagander2008-11-24

* Move FAQ_AIX information to installation instructions.Peter Eisentraut2008-11-24
| | | | | | The information on why the shared libraries are built the way they are was not relevant to end users and has been made a mailing list archive link in Makefile.shlib.
* Add support for matching wildcard server certificates to the new SSL code.Magnus Hagander2008-11-24
| | | | | This uses the function fnmatch() which is not available on all platforms (notably Windows), so import the implementation from NetBSD into src/port.

* Teach RequestCheckpoint() to wait and retry a few times if it can't signalTom Lane2008-11-23
| | | | | | | | the bgwriter immediately. This covers the case where the bgwriter is still starting up, as seen in a recent buildfarm failure. In future it might also assist with clean recovery after a bgwriter termination and restart --- right now the postmaster treats early bgwriter exit as a system crash, but that might not always be so.
* Switch the planner over to treating qualifications of a JOIN_SEMI join asTom Lane2008-11-22
| | | | | | | | | | | | | | | | | | | though it is an inner rather than outer join type. This essentially means that we don't bother to separate "pushed down" qual conditions from actual join quals at a semijoin plan node; which is okay because the restrictions of SQL syntax make it impossible to have a pushed-down qual that references the inner side of a semijoin. This allows noticeably better optimization of IN/EXISTS cases than we had before, since the equivalence-class machinery can now use those quals. Also fix a couple of other mistakes that had essentially disabled the ability to unique-ify the inner relation and then join it to just a subset of the left-hand relations. An example case using the regression database is select * from tenk1 a, tenk1 b where (a.unique1,b.unique2) in (select unique1,unique2 from tenk1 c); which is planned reasonably well by 8.3 and earlier but had been forcing a cartesian join of a/b in CVS HEAD.

* Fix breakage of bitmap scan plan creation for special index operators suchTom Lane2008-11-20
| | | | | | | | as LIKE. I oversimplified this code when removing support for plan-time determination of index operator lossiness back in April --- I had thought create_bitmap_subplan could stop returning two separate lists of qual conditions, but it still must so that we can treat special operators correctly in create_bitmap_scan_plan. Per report from Rushabh Lathia.
* Don't pass strings directly to errdetail() and errhint() - useMagnus Hagander2008-11-20

* Add support for using SSL client certificates to authenticate to theMagnus Hagander2008-11-20

* Control client certificate requesting with the pg_hba option "clientcert"Magnus Hagander2008-11-20
| | | | instead of just relying on the root certificate file to be present.
* Rethink the way FSM truncation works. Instead of WAL-logging FSMHeikki Linnakangas2008-11-19
| | | | | | | | | | | | | | | truncations in FSM code, call FreeSpaceMapTruncateRel from smgr_redo. To make that cleaner from modularity point of view, move the WAL-logging one level up to RelationTruncate, and move RelationTruncate and all the related WAL-logging to new src/backend/catalog/storage.c file. Introduce new RelationCreateStorage and RelationDropStorage functions that are used instead of calling smgrcreate/smgrscheduleunlink directly. Move the pending rel deletion stuff from smgrcreate/smgrscheduleunlink to the new functions. This leaves smgr.c as a thin wrapper around md.c; all the transactional stuff is now in storage.c. This will make it easier to add new forks with similar truncation logic, like the visibility map.
* Fix compiler warning "res may be used uninitialized in this function".Teodor Sigaev2008-11-19
| | | | | Actually, it can't but some compilers are not smart enough. Per Peter Eisentraut gripe.
* Change this script to Perl 5 style. Add support for multiple refnames.Peter Eisentraut2008-11-19
| | | | | | Sort the output by command name. This previously only worked by source file name, which doesn't always match the command name exactly. And it certainly won't work for multiple refnames.
* Fix define_custom_variable so that SUSET custom variables behaveTom Lane2008-11-19
| | | | | somewhat reasonably. It's not perfect, but it beats the kluge proposed in the auto-explain patch ...
* Some infrastructure changes for the upcoming auto-explain contrib module:Tom Lane2008-11-19
| | | | | | | | | | | | | | | | | | | | | | * Refactor explain.c slightly to export a convenient-to-use subroutine for printing EXPLAIN results. * Provide hooks for plugins to get control at ExecutorStart and ExecutorEnd as well as ExecutorRun. * Add some minimal support for tracking the total runtime of ExecutorRun. This code won't actually do anything unless a plugin prods it to. * Change the API of the DefineCustomXXXVariable functions to allow nonzero "flags" to be specified for a custom GUC variable. While at it, also make the "bootstrap" default value for custom GUCs be explicitly specified as a parameter to these functions. This is to eliminate confusion over where the default comes from, as has been expressed in the past by some users of the custom-variable facility. * Refactor GUC code a bit to ensure that a custom variable gets initialized to something valid (like its default value) even if the placeholder value was invalid.
