* Further planner/optimizer cleanups. Move all set_tlist_referencesTom Lane1999-08-221-4/+4
| | | | | | | | | | and fix_opids processing to a single recursive pass over the plan tree executed at the very tail end of planning, rather than haphazardly here and there at different places. Now that tlist Vars do not get modified until the very end, it's possible to get rid of the klugy var_equal and match_varid partial-matching routines, and just use plain equal() throughout the optimizer. This is a step towards allowing merge and hash joins to be done on expressions instead of only Vars ...
* Major revision of sort-node handling: push knowledge of queryTom Lane1999-08-211-3/+2
| | | | | | | | | | | | | sort order down into planner, instead of handling it only at the very top level of the planner. This fixes many things. An explicit sort is now avoided if there is a cheaper alternative (typically an indexscan) not only for ORDER BY, but also for the internal sort of GROUP BY. It works even when there is no other reason (such as a WHERE condition) to consider the indexscan. It works for indexes on functions. It works for indexes on functions, backwards. It's just so cool... CAUTION: I have changed the representation of SortClause nodes, therefore THIS UPDATE BREAKS STORED RULES. You will need to initdb.

* heap_fetch requires buffer pointer, must be released; heap_getnextBruce Momjian1998-08-191-18/+10
| | | | | | | | | | | | | no longer returns buffer pointer, can be gotten from scan; descriptor; bootstrap can create multi-key indexes; pg_procname index now is multi-key index; oidint2, oidint4, oidname are gone (must be removed from regression tests); use System Cache rather than sequential scan in many places; heap_modifytuple no longer takes buffer parameter; remove unused buffer parameter in a few other functions; oid8 is not index-able; remove some use of single-character variable names; cleanup Buffer variables usage and scan descriptor looping; cleaned up allocation and freeing of tuples; 18k lines of diff;

* Allow floating point constants for "def_arg" numeric arguments.Thomas G. Lockhart1998-07-081-6/+7
| | | | | | Used in the generic "CREATE xxx" parsing. Do some automatic type conversion for inserts from other columns. Previous trouble with "resjunk" regression test remains for now.
* Remove un-needed braces around single statements.Bruce Momjian1998-06-151-13/+1
|
* Do type conversion to match columns in UNION clauses.Thomas G. Lockhart1998-05-291-456/+16
| | | | | | | | | | | 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.
* Add capabilities for automatic type conversion.Thomas G. Lockhart1998-05-091-119/+727

* This patch...Bruce Momjian1998-04-271-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
