Jan Wieck	57d8080a40	TOAST ... WARNING: This is actually broken - we have self-deadlocks due to concurrent changes in buffer management. Vadim and me are working on it. Jan	26 years ago
Tom Lane	1aebc3618a	First phase of memory management rewrite (see backend/utils/mmgr/README ... for details). It doesn't really do that much yet, since there are no short-term memory contexts in the executor, but the infrastructure is in place and long-term contexts are handled reasonably. A few long- standing bugs have been fixed, such as 'VACUUM; anything' in a single query string crashing. Also, out-of-memory is now considered a recoverable ERROR, not FATAL. Eliminate a large amount of crufty, now-dead code in and around memory management. Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and backend startup.	26 years ago
Bruce Momjian	946e80c435	Final #include cleanup.	26 years ago
Bruce Momjian	3357e1d29e	Back out pg_shadow changes to allow create table and locking permissions.	26 years ago
Bruce Momjian	85add42a57	I have large database and with this DB work more users and I very need ... more restriction for fretful users. The current PG allow define only NO-CREATE-DB and NO-CREATE-USER restriction, but for some users I need NO-CREATE-TABLE and NO-LOCK-TABLE. This patch add to current code NOCREATETABLE and NOLOCKTABLE feature: CREATE USER username [ WITH [ SYSID uid ] [ PASSWORD 'password' ] ] [ CREATEDB | NOCREATEDB ] [ CREATEUSER | NOCREATEUSER ] -> [ CREATETABLE | NOCREATETABLE ] [ LOCKTABLE | NOLOCKTABLE ] ...etc. If CREATETABLE or LOCKTABLE is not specific in CREATE USER command, as default is set CREATETABLE or LOCKTABLE (true). A user with NOCREATETABLE restriction can't call CREATE TABLE or SELECT INTO commands, only create temp table is allow for him. Karel	26 years ago

Tom Lane	091126fa28	Generated header files parse.h and fmgroids.h are now copied into ... the src/include tree, so that -I backend is no longer necessary anywhere. Also, clean up some bit rot in contrib tree.	26 years ago
Tom Lane	18952f6744	Second round of fmgr changes: triggers are now invoked in new style, ... CurrentTriggerData is history.	26 years ago
Tom Lane	0a7fb4e918	First round of changes for new fmgr interface. fmgr itself and the ... key call sites are changed, but most called functions are still oldstyle. An exception is that the PL managers are updated (so, for example, NULL handling now behaves as expected in plperl and plpgsql functions). NOTE initdb is forced due to added column in pg_proc.	26 years ago

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.	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
