* Extend r-tree operator classes to handle Y-direction tests equivalentTom Lane2005-06-24
| | | | | | | | | | | | | | | to the existing X-direction tests. An rtree class now includes 4 actual 2-D tests, 4 1-D X-direction tests, and 4 1-D Y-direction tests. This involved adding four new Y-direction test operators for each of box and polygon; I followed the PostGIS project's lead as to the names of these operators. NON BACKWARDS COMPATIBLE CHANGE: the poly_overleft (&<) and poly_overright (&>) operators now have semantics comparable to box_overleft and box_overright. This is necessary to make r-tree indexes work correctly on polygons. Also, I changed circle_left and circle_right to agree with box_left and box_right --- formerly they allowed the boundaries to touch. This isn't actually essential given the lack of any r-tree opclass for circles, but it seems best to sync all the definitions while we are at it.

* Remove overspecification of precision of CURRENT_TIMESTAMP, LOCALTIMESTAMP,Tom Lane2005-06-24
| | | | | | | | | | | CURRENT_TIME, and LOCALTIME: now they just produce "timestamptz" not "timestamptz(6)", etc. This makes the behavior more consistent with our choice to not assign a specific default precision to column datatypes. It should also save a few cycles at runtime due to not having to invoke the round-to-given-precision functions. I also took the opportunity to translate CURRENT_TIMESTAMP into "now()" instead of an invocation of the timestamptz input converter --- this should save a few cycles too.

* Fix rtree and contrib/rtree_gist search behavior for the 1-D box andTom Lane2005-06-24
| | | | | | | | | | polygon operators (<<, &<, >>, &>). Per ideas originally put forward by andrew@supernews and later rediscovered by moi. This patch just fixes the existing opclasses, and does not add any new behavior as I proposed earlier; that can be sorted out later. In principle this could be back-patched, since it changes only search behavior and not system catalog entries nor rtree index contents. I'm not currently planning to do that, though, since I think it could use more testing.
* Move findoidjoins out of contrib and into src/tools, which is a moreTom Lane2005-06-23
| | | | | logical place for it since it is of no use to users. Per recent discussions on cleaning up contrib.
* Make REINDEX DATABASE do what one would expect, namely reindex all indexesTom Lane2005-06-22
| | | | | | | in the database. The old behavior (reindex system catalogs only) is now available as REINDEX SYSTEM. I did not add the complementary REINDEX USER case since there did not seem to be consensus for this, but it would be trivial to add later. Per recent discussions.
* Fix the mechanism for reporting the original table OID and column numberTom Lane2005-06-22
| | | | | of columns of a query result so that it can "see through" cursors and prepared statements. Per gripe a couple months back from John DeSoi.
* Add a validator function for plperl. Andrew DunstanTom Lane2005-06-22

* Add a hack requested by the JDBC driver writers: when a function'sTom Lane2005-06-22
| | | | | | | | | argument list contains parameter symbols ($n) declared as type VOID, discard these arguments. This allows the driver to avoid renumbering mixed IN and OUT argument placeholders (the JDBC syntax involves writing ? for both IN and OUT parameters, but on the server side we don't think that OUT parameters are arguments). This doesn't break any currently- useful cases since VOID is not used as an input argument type.
* Fix bug in CONTINUE statement for PL/pgSQL: when we continue a loop,Neil Conway2005-06-22
| | | | | | | | we need to be careful to reset rc to PLPGSQL_RC_OK, depending on how the loop's logic is structured. If we continue a loop but it then exits without executing the loop's body again, we want to return PLPGSQL_RC_OK to our caller. Enhance the regression tests to catch this problem. Per report from Michael Fuhr.
* Correct some code in pg_restore when reading the header of a tar archive:Neil Conway2005-06-22
| | | | | | | | | | | | | (1) The code doesn't initialize `sum', so the initial "does the checksum match?" test is wrong. (2) The loop that is intended to check for a "null block" just checks the first byte of the tar block 512 times, rather than each of the 512 bytes one time (!), which I'm guessing was the intent. It was only through sheer luck that this worked in the first place. Per Coverity static analysis performed by EnterpriseDB.
* More trivial dead code removal: in int_to_roman(), checking for "num == -1"Neil Conway2005-06-22
| | | | | | | | is redundant after a check has already been made for "num < 0". The "set" variable can also be removed, as it is now no longer used. Per checking with Karel, this is the right fix. Per Coverity static analysis performed by EnterpriseDB.
* Add a CONTINUE statement to PL/PgSQL, which can be used to begin theNeil Conway2005-06-22
| | | | | next iteration of a loop. Update documentation and add regression tests. Patch from Pavel Stehule, reviewed by Neil Conway.
* pg_dump can now dump large objects even in plain-text output mode, byTom Lane2005-06-21
| | | | | | using the recently added lo_create() function. The restore logic in pg_restore is greatly simplified as well, since there's no need anymore to try to adjust database references to match a new set of blob OIDs.
* Fix pg_dumpall to do the right thing with "postgres" database, perTom Lane2005-06-21
| | | | | Dave Page. Also, cause it to emit rather than ignore any ACL and datconfig options that may be set for these two databases.
* Cause initdb to create a third standard database "postgres", whichTom Lane2005-06-21
| | | | | | | | | | | | | | unlike template0 and template1 does not have any special status in terms of backend functionality. However, all external utilities such as createuser and createdb now connect to "postgres" instead of template1, and the documentation is changed to encourage people to use "postgres" instead of template1 as a play area. This should fix some longstanding gotchas involving unexpected propagation of database objects by createdb (when you used template1 without understanding the implications), as well as ameliorating the problem that CREATE DATABASE is unhappy if anyone else is connected to template1. Patch by Dave Page, minor editing by Tom Lane. All per recent pghackers discussions.
* Fix a potential backend crash during authentication when parsing aNeil Conway2005-06-21
| | | | | | | malformed ident map file. This was introduced by the linked list rewrite in 8.0 -- mea maxima culpa. Per Coverity static analysis performed by EnterpriseDB.
* Trivial dead code removal: in CreateSchemaCommand(), 'owner_name' isNeil Conway2005-06-21
| | | | | | | | only used in one branch of an if statement, so we can move its declaration to that block. This also avoids an unnecessary syscache lookup. Per Coverity static analysis performed by EnterpriseDB.
* Trivial dead code removal: in _complete_from_query(), 'text' cannot beNeil Conway2005-06-21
| | | | | | | NULL (e.g. due to the preceding strlen()). Therefore we needn't recheck this before initializing 'e_text'. Per Coverity static analysis performed by EnterpriseDB.
* Trivial dead code removal: in makeObjectName(), name1 must be non-NULLNeil Conway2005-06-21
| | | | | | | (due to the preceding strlen(), for example), so we needn't recheck this before invoking pg_mbcliplen(). Per Coverity static analysis performed by EnterpriseDB.
* exec_eval_datum leaks memory when dealing with ROW or REC values.Tom Lane2005-06-20
| | | | | | | It never leaked memory before PG 8.0, so none of the callers are expecting this. Cleanest fix seems to be to make it allocate the needed memory in estate->eval_econtext, where it will be cleaned up by the next exec_eval_cleanup. Per report from Bill Rugolsky.
* Remove read_file/write_file tests. These were originally intended toTom Lane2005-06-20
| | | | | | | | | *fail*, to test that plpython didn't allow untrusted operations. When we changed plpython to plpythonu because python didn't actually have a secure sandbox mode, someone (probably me :-() misinterpreted the tests as checking whether Python's file I/O works. Which is a stupid thing for us to be testing. Remove it so we don't clutter the filesystem with random temporary files.
* plpgsql's exec_assign_value() freed the old value of a variable beforeTom Lane2005-06-20
| | | | | | | copying/converting the new value, which meant that it failed badly on "var := var" if var is of pass-by-reference type. Fix this and a similar hazard in exec_move_row(); not sure that the latter can manifest before 8.0, but patch it all the way back anyway. Per report from Dave Chapeskie.
* Avoid WAL-logging individual tuple insertions during CREATE TABLE ASTom Lane2005-06-20
| | | | | | (a/k/a SELECT INTO). Instead, flush and fsync the whole relation before committing. We do still need the WAL log when PITR is active, however. Simon Riggs and Tom Lane.

| | | | | | | scankeys arrays that it needs can never have more than INDEX_MAX_KEYS entries, so it's reasonable to just allocate them as fixed-size local arrays, and save the cost of palloc/pfree. Not a huge savings, but a cycle saved is a cycle earned ...

* Simplify uses of readdir() by creating a function ReadDir() thatTom Lane2005-06-19
| | | | | | | includes error checking and an appropriate ereport(ERROR) message. This gets rid of rather tedious and error-prone manipulation of errno, as well as a Windows-specific bug workaround, at more than a dozen call sites. After an idea in a recent patch by Heikki Linnakangas.
* Arrange to fsync two-phase-commit state files only during checkpoints;Tom Lane2005-06-19

* When using C-string lookup keys in a dynahash.c hash table, use strncpy()Tom Lane2005-06-18

* Add a time-of-preparation column to the pg_prepared_xacts view, per anTom Lane2005-06-18
| | | | | | | | | | old suggestion by Oliver Jowett. Also, add a transaction column to the pg_locks view to show the xid of each transaction holding or awaiting locks; this allows prepared transactions to be properly associated with the locks they own. There was already a column named 'transaction', and I chose to rename it to 'transactionid' --- since this column is new in the current devel cycle there should be no backwards compatibility issue to worry about.
