* ALTER TABLE rewrite. New cool stuff:Tom Lane2004-05-05
| | | | | | | | | | | | | | | | | | | | * ALTER ... ADD COLUMN with defaults and NOT NULL constraints works per SQL spec. A default is implemented by rewriting the table with the new value stored in each row. * ALTER COLUMN TYPE. You can change a column's datatype to anything you want, so long as you can specify how to convert the old value. Rewrites the table. (Possible future improvement: optimize no-op conversions such as varchar(N) to varchar(N+1).) * Multiple ALTER actions in a single ALTER TABLE command. You can perform any number of column additions, type changes, and constraint additions with only one pass over the table contents. Basic documentation provided in ALTER TABLE ref page, but some more docs work is needed. Original patch from Rod Taylor, additional work from Tom Lane.
* Remove the last traces of Joe Hellerstein's "xfunc" optimization. PatchNeil Conway2004-04-25

* Complete TODO item:Bruce Momjian2004-04-19
| | | | | | | | | | | | | | o -Allow dump/load of CSV format This adds new keywords to COPY and \copy: CSV - enable CSV mode (comma separated variable) QUOTE - specify quote character ESCAPE - specify escape character FORCE - force quoting of specified column LITERAL - suppress null comparison for columns Doc changes included. Regression updates coming from Andrew.

OK, here is a patch that implements #1. Here is sample output: test=> set client_min_messages = 'log'; SET test=> set log_statement = 'mod'; SET test=> select 1; ?column? ---------- 1 (1 row) test=> update test set x=1; LOG: statement: update test set x=1; ERROR: relation "test" does not exist test=> update test set x=1; LOG: statement: update test set x=1; ERROR: relation "test" does not exist test=> copy test from '/tmp/x'; LOG: statement: copy test from '/tmp/x'; ERROR: relation "test" does not exist test=> copy test to '/tmp/x'; ERROR: relation "test" does not exist test=> prepare xx as select 1; PREPARE test=> prepare xx as update x set y=1; LOG: statement: prepare xx as update x set y=1; ERROR: relation "x" does not exist test=> explain analyze select 1;; QUERY PLAN ------------------------------------------------------------------------------------ Result (cost=0.00..0.01 rows=1 width=0) (actual time=0.006..0.007 rows=1 loops=1) Total runtime: 0.046 ms (2 rows) test=> explain analyze update test set x=1; LOG: statement: explain analyze update test set x=1; ERROR: relation "test" does not exist test=> explain update test set x=1; ERROR: relation "test" does not exist It checks PREPARE and EXECUTE ANALYZE too. The log_statement values are 'none', 'mod', 'ddl', and 'all'. For 'all', it prints before the query is parsed, and for ddl/mod, it does it right after parsing using the node tag (or command tag for CREATE/ALTER/DROP), so any non-parse errors will print after the log line.
* Replace max_expr_depth parameter with a max_stack_depth parameter thatTom Lane2004-03-24
| | | | | | is measured in kilobytes and checked against actual physical execution stack depth, as per my proposal of 30-Dec. This gives us a fairly bulletproof defense against crashing due to runaway recursive functions.
* Upgrade ALTER TABLE DROP COLUMN so that it can drop an OID column, andTom Lane2004-03-23
| | | | | | | | | remove separate implementation of ALTER TABLE SET WITHOUT OIDS in favor of doing a regular DROP. Also, cause CREATE TABLE to account completely correctly for the inheritance status of the OID column. This fixes problems with dropping OID columns that have dependencies, as noted by Christopher Kings-Lynne, as well as making sure that you can't drop an OID column that was inherited from a parent.

* Restructure smgr API as per recent proposal. smgr no longer depends onTom Lane2004-02-10

Internal restructuring in md.c to remove the not-very-useful array of MdfdVec objects --- might as well just use pointers. Also remove the long-dead 'persistent main memory' storage manager (mm.c), since it seems quite unlikely to ever get resurrected.

| | | | | | | Make btree index creation and initial validation of foreign-key constraints use maintenance_work_mem rather than work_mem as their memory limit. Add some code to guc.c to allow these variables to be referenced by their old names in SHOW and SET commands, for backwards compatibility.

NOTIFY thought it could do its thing if transaction blockState is TBLOCK_DEFAULT, but in reality it had better check the low-level transaction state is TRANS_DEFAULT as well. Formerly it was not possible to wait for the client in a state where the first is true and the second is not ... but now we can have such a state. Minor cleanup in StartTransaction() as well.

* This patch fixes an obvious bug in the "should I print the duration ofBruce Momjian2003-09-29

* Get rid of ReferentialIntegritySnapshotOverride by extending Executor APITom Lane2003-09-25

* Message editing: remove gratuitous variations in message wording, standardizePeter Eisentraut2003-09-25

* Repair some REINDEX problems per recent discussions. The relcache isTom Lane2003-09-24
| | | | | | | | | | | | | now able to cope with assigning new relfilenode values to nailed-in-cache indexes, so they can be reindexed using the fully crash-safe method. This leaves only shared system indexes as special cases. Remove the 'index deactivation' code, since it provides no useful protection in the shared- index case. Require reindexing of shared indexes to be done in standalone mode, but remove other restrictions on REINDEX. -P (IgnoreSystemIndexes) now prevents using indexes for lookups, but does not disable index updates. It is therefore safe to allow from PGOPTIONS. Upshot: reindexing system catalogs can be done without a standalone backend for all cases except shared catalogs.
* Reconsider placement of MemoryContextCheck() call --- do after commit,Tom Lane2003-09-14

* Some "feature not supported" errors are better syntax errors, because thePeter Eisentraut2003-09-09
