* Improve error message wording in unary_op_error() --- suggest thatTom Lane2000-03-18
| | | | | | problem could be lack of parentheses. This addresses cases like X UserOp UserOp Y, which will be parsed as (X UserOp) UserOp Y, whereas what likely was wanted was X UserOp (UserOp Y).
* Further fixes for bogus list-slinging, scribbling on input, etc in typeTom Lane2000-03-11
| | | | | | | | | coercion code. I'm beginning to wonder why we have separate candidate selection routines for functions, operators, and aggregates --- shouldn't this code all be unified? But meanwhile, SELECT 'a' LIKE 'a'; finally works; the code for dealing with unknown input types for operators was pretty busted.
* Fix poorly worded error messages for unary operator type resolutionTom Lane2000-02-27
| | | | | | | failures. Fix some outright bugs too, including a reference to uninitialized memory that would cause failures like this one: select -('1234567890.1234567'::text); ERROR: Unable to locate type oid 2139062143 in catalog

| | | | | | | Make all system indexes unique. Make all cache loads use system indexes. Rename *rel to *relid in inheritance tables. Rename cache names to be clearer.
* Mega-commit to make heap_open/heap_openr/heap_close take anTom Lane1999-09-18
| | | | | | | | | | | | | | | | | 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.
* Clean up some bugs in oper_select_candidate(), notably theTom Lane1999-08-26
| | | | | | last loop which would return the *first* surviving-to-that-point candidate regardless of which one actually passed the test. This was producing such curious results as 'oid % 2' getting translated to 'int2(oid) % 2'.
* Remove bogus code in oper_exact --- if it didn't find an exactTom Lane1999-08-23
| | | | | | | | | match then it tried for a self-commutative operator with the reversed input data types. This is pretty silly; there could never be such an operator, except maybe in binary-compatible-type scenarios, and we have oper_inexact for that. Besides which, the oprsanity regress test would complain about such an operator. Remove nonfunctional code and simplify routine calling convention accordingly.

* Do type conversion to match columns in UNION clauses.Thomas G. Lockhart1998-05-29
| | | | | | | | | | | Currently force the type to match the _first_ select in the union. Move oper_select_candidate() from parse_func.c to parse_oper.c. Throw error inside of oper_inexact() if no match for binary operators. Check more carefully that types can be coerced even if there is only one candidate operator in oper_inexact(). Fix up error messages for more uniform look. Remove unused code. Fix up comments.

* This patch...Bruce Momjian1998-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
