Tom Lane	eabc714a91	Reimplement parsing and storage of default expressions and constraint ... expressions in CREATE TABLE. There is no longer an emasculated expression syntax for these things; it's full a_expr for constraints, and b_expr for defaults (unfortunately the fact that NOT NULL is a part of the column constraint syntax causes a shift/reduce conflict if you try a_expr. Oh well --- at least parenthesized boolean expressions work now). Also, stored expression for a column default is not pre-coerced to the column type; we rely on transformInsertStatement to do that when the default is actually used. This means "f1 datetime default 'now'" behaves the way people usually expect it to. BTW, all the support code is now there to implement ALTER TABLE ADD CONSTRAINT and ALTER TABLE ADD COLUMN with a default value. I didn't actually teach ALTER TABLE to call it, but it wouldn't be much work.	27 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.	27 years ago

Bruce Momjian	09baa3cc81	This patch... ... 1. Removes the unnecessary "#define AbcRegProcedure 123"'s from pg_proc.h. 2. Changes those #defines to use the names already defined in fmgr.h. 3. Forces the make of fmgr.h in backend/Makefile instead of having it made as a dependency in access/common/Makefile *hack*hack*hack* 4. Rearranged the #includes to a less helter-skelter arrangement, also changing <file.h> to "file.h" to signify a non-system header. 5. Removed "pg_proc.h" from files where its only purpose was for the #defines removed in item #1. 6. Added "fmgr.h" to each file changed for completeness sake. Turns out that #6 was not necessary for some files because fmgr.h was being included in a roundabout way SIX levels deep by the first include. "access/genam.h" ->"access/relscan.h" ->"utils/rel.h" ->"access/strat.h" ->"access/skey.h" ->"fmgr.h" So adding fmgr.h really didn't add anything to the compile, hopefully just made it clearer to the programmer.
