Bruce Momjian	7acc237744	This patch implements ORACLE's COMMENT SQL command. ... >From the ORACLE 7 SQL Language Reference Manual: ----------------------------------------------------- COMMENT Purpose: To add a comment about a table, view, snapshot, or column into the data dictionary. Prerequisites: The table, view, or snapshot must be in your own schema or you must have COMMENT ANY TABLE system privilege. Syntax: COMMENT ON [ TABLE table ] | [ COLUMN table.column] IS 'text' You can effectively drop a comment from the database by setting it to the empty string ''. ----------------------------------------------------- Example: COMMENT ON TABLE workorders IS 'Maintains base records for workorder information'; COMMENT ON COLUMN workorders.hours IS 'Number of hours the engineer worked on the task'; to drop a comment: COMMENT ON COLUMN workorders.hours IS ''; The current patch will simply perform the insert into pg_description, as per the TODO. And, of course, when the table is dropped, any comments relating to it or any of its attributes are also dropped. I haven't looked at the ODBC source yet, but I do know from an ODBC client standpoint that the standard does support the notion of table and column comments. Hopefully the ODBC driver is already fetching these values from pg_description, but if not, it should be trivial. Hope this makes the grade, Mike Mascari (mascarim@yahoo.com)	26 years ago

Tom Lane	bd272cace6	Mega-commit to make heap_open/heap_openr/heap_close take an ... additional argument specifying the kind of lock to acquire/release (or 'NoLock' to do no lock processing). Ensure that all relations are locked with some appropriate lock level before being examined --- this ensures that relevant shared-inval messages have been processed and should prevent problems caused by concurrent VACUUM. Fix several bugs having to do with mismatched increment/decrement of relation ref count and mismatched heap_open/close (which amounts to the same thing). A bogus ref count on a relation doesn't matter much *unless* a SI Inval message happens to arrive at the wrong time, which is probably why we got away with this sloppiness for so long. Repair missing grab of AccessExclusiveLock in DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi. Recommend 'make clean all' after pulling this update; I modified the Relation struct layout slightly. Will post further discussion to pghackers list shortly.	26 years ago

Marc G. Fournier	38a5bda208	primary key support cleanups from D'Arcy...	27 years ago
Bruce Momjian	c91dbcc5c7	The following patch finishes primary key support. Previously, when ... a field was labelled as a primary key, the system automatically created a unique index on the field. This patch extends it so that the index has the indisprimary field set. You can pull a list of primary keys with the followiing select. SELECT pg_class.relname, pg_attribute.attname FROM pg_class, pg_attribute, pg_index WHERE pg_class.oid = pg_attribute.attrelid AND pg_class.oid = pg_index.indrelid AND pg_index.indkey[0] = pg_attribute.attnum AND pg_index.indisunique = 't'; There is nothing in this patch that modifies the template database to set the indisprimary attribute for system tables. Should they be changed or should we only be concerned with user tables? D'Arcy	27 years ago

Bruce Momjian	c0b01461db	o note that now pg_database has a new attribuite "encoding" even ... if MULTIBYTE is not enabled. So be sure to run initdb. o these patches are made against the latest source tree (after Bruce's massive patch, I think) BTW, I noticed that after running regression, the oid field of pg_type seems disappeared. regression=> select oid from pg_type; ERROR: attribute 'oid' not found this happens after the constraints test. This occures with/without my patches. strange... o pg_database_mb.h, pg_class_mb.h, pg_attribute_mb.h are no longer used, and shoud be removed. o GetDatabaseInfo() in utils/misc/database.c removed (actually in #ifdef 0). seems nobody uses. t-ishii@sra.co.jp	27 years ago
