| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'd have to disagree with regards to the memory leaks not being worth a mention - any such leak can cause problems when the PostgreSQL installation is either unattended, long-living andor has very high connection levels. Half a kilobyte on start-up isn't negligible in this light. Regards, Lee.

Here is a patch for the above, including a documentation update. It creates a new GUC variable "preload_libraries", that accepts a list in the form: preload_libraries = '$libdir/mylib1:initfunc,$libdir/mylib2' If ":initfunc" is omitted or not found, no initialization function is executed, but the library is still preloaded. If "$libdir/mylib" isn't found, the postmaster refuses to start. In my testing with PL/R, it reduces the first call to a PL/R function (after connecting) from almost 2 seconds, down to about 8 ms.

* Merge the last few variable.c configuration variables into the genericTom Lane2002-05-17
| | | | | | | | | GUC support. It's now possible to set datestyle, timezone, and client_encoding from postgresql.conf and per-database or per-user settings. Also, implement rollback of SET commands that occur in a transaction that later fails. Create a SET LOCAL var = value syntax that sets the variable only for the duration of the current transaction. All per previous discussions in pghackers.
* Accept SET SESSION AUTHORIZATION DEFAULT and RESET SESSION AUTHORIZATIONTom Lane2002-05-06
| | | | | | | | to reset session userid to the originally-authenticated name. Also, relax SET SESSION AUTHORIZATION to allow specifying one's own username even if one is not superuser, so as to avoid unnecessary error messages when loading a pg_dump file that uses this command. Per discussion from several months ago.
* Create an internal semaphore API that is not tied to SysV semaphores.Tom Lane2002-05-05
| | | | | | As proof of concept, provide an alternate implementation based on POSIX semaphores. Also push the SysV shared-memory implementation into a separate file so that it can be replaced conveniently.

* Support toasting of shared system relations, and provide toast tables forTom Lane2002-04-27
| | | | | | | | | pg_database, pg_shadow, pg_group, all of which now have potentially-long fields. Along the way, get rid of SharedSystemRelationNames list: shared rels are now identified in their include/pg_catalog/*.h files by a BKI_SHARED_RELATION macro, while indexes and toast rels inherit sharedness automatically from their parent table. Fix some bugs with failure to detoast pg_group.grolist during ALTER GROUP.

* Set optreset on platforms that have it before launching postmasterTom Lane2001-10-19
| | | | | | subprocesses; perhaps this will fix portability problem just noted by Lockhart. Also, move test for bad permissions of DataDir to a more logical place.
* Ensure that all startup paths (postmaster, standalone postgres, orTom Lane2001-10-19
| | | | | | | bootstrap) check for a valid PG_VERSION file before looking at anything else in the data directory. This fixes confusing error report when trying to start current sources in a pre-7.1 data directory. Per trouble report from Rich Shepard 10/18/01.
* Add a new function "pg_client_encoding" which returns the current clientTatsuo Ishii2001-10-12

* Make the world somewhat safe for (not from) DELETE FROM pg_shadow;Peter Eisentraut2001-09-08
| | | | | | | | | | | | | | | | | | | | | Assign the fixed user id 1 to the user created by initdb. A stand-alone backend will always set the user id to 1. (Consequently, the name of that user is no longer important.) In stand-alone mode, the user id 1 will have implicit superuser status, to allow repairs even if there are no users defined. Print a warning message when starting in stand-alone mode when no users are defined. Disallow dropping the current user and session user. Granting/revoking superuser status also grants/revokes usecatupd. (Previously, it would never grant it back. This could lead to "deadlocks".) CREATE USER and CREATE GROUP will start allocating user ids at 100 (unless explicitly specified), to prevent accidental creation of a superuser (plus some room for future extensions).

| | | | | | | | | | a new postmaster child process. This should eliminate problems with authentication blocking (e.g., ident, SSL init) and also reduce problems with the accept queue filling up under heavy load. The option to send elog output to a different file per backend (postgres -o) has been disabled for now because the initialization would have to happen in a different order and it's not clear we want to keep this anyway.
* has_table_privilege functions from Joe Conway (with some kibitzing fromTom Lane2001-06-14

* Adjust WAL code so that checkpoints truncate the xlog at the previousTom Lane2001-06-06
| | | | | | | | | | | | checkpoint's redo pointer, not its undo pointer, per discussion in pghackers a few days ago. No point in hanging onto undo information until we have the ability to do something with it --- and this solves a rather large problem with log space for long-running transactions. Also, change all calls of write() to detect the case where write returned a count less than requested, but failed to set errno. Presume that this situation indicates ENOSPC, and give the appropriate error message, rather than a random message associated with the previous value of errno.

* XLOG (and related) changes:Tom Lane2001-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Store two past checkpoint locations, not just one, in pg_control. On startup, we fall back to the older checkpoint if the newer one is unreadable. Also, a physical copy of the newest checkpoint record is kept in pg_control for possible use in disaster recovery (ie, complete loss of pg_xlog). Also add a version number for pg_control itself. Remove archdir from pg_control; it ought to be a GUC parameter, not a special case (not that it's implemented yet anyway). * Suppress successive checkpoint records when nothing has been entered in the WAL log since the last one. This is not so much to avoid I/O as to make it actually useful to keep track of the last two checkpoints. If the things are right next to each other then there's not a lot of redundancy gained... * Change CRC scheme to a true 64-bit CRC, not a pair of 32-bit CRCs on alternate bytes. Polynomial borrowed from ECMA DLT1 standard. * Fix XLOG record length handling so that it will work at BLCKSZ = 32k. * Change XID allocation to work more like OID allocation. (This is of dubious necessity, but I think it's a good idea anyway.) * Fix a number of minor bugs, such as off-by-one logic for XLOG file wraparound at the 4 gig mark. * Add documentation and clean up some coding infelicities; move file format declarations out to include files where planned contrib utilities can get at them. * Checkpoint will now occur every CHECKPOINT_SEGMENTS log segments or every CHECKPOINT_TIMEOUT seconds, whichever comes first. It is also possible to force a checkpoint by sending SIGUSR1 to the postmaster (undocumented feature...) * Defend against kill -9 postmaster by storing shmem block's key and ID in postmaster.pid lockfile, and checking at startup to ensure that no processes are still connected to old shmem block (if it still exists). * Switch backends to accept SIGQUIT rather than SIGUSR1 for emergency stop, for symmetry with postmaster and xlog utilities. Clean up signal handling in bootstrap.c so that xlog utilities launched by postmaster will react to signals better. * Standalone bootstrap now grabs lockfile in target directory, as added insurance against running it in parallel with live postmaster.
