Bruce Momjian	da5aba105f	Remove Ops parameter from STATRELID cache lookup, for Tom Lane and ... optimizer.	26 years ago
Tom Lane	27fee810ff	Replace SearchSysCacheGetAttribute with SysCacheGetAttr, which fetches ... an attribute of a tuple previously fetched with SearchSysCacheTuple. This avoids a lot of redundant cache lookups, particularly in selfuncs.c. Also, remove SearchSysCacheStruct, which was unused and grotty.	26 years ago
Tom Lane	8449df8a67	First cut at unifying regular selectivity estimation with indexscan ... selectivity estimation wasn't right. This is better...	26 years ago
Tom Lane	71ed7eb494	Revise handling of index-type-specific indexscan cost estimation, per ... pghackers discussion of 5-Jan-2000. The amopselect and amopnpages estimators are gone, and in their place is a per-AM amcostestimate procedure (linked to from pg_am, not pg_amop).	26 years ago
Tom Lane	584e646ad8	Fix a passel of problems with incorrect calls to typinput and typoutput ... functions, which would lead to trouble with datatypes that paid attention to the typelem or typmod parameters to these functions. In particular, incorrect code in pg_aggregate.c explains the platform-specific failures that have been reported in NUMERIC avg().	26 years ago
Peter Eisentraut	1cd4c14116	Fixed all elog related warnings, as well as a few others.	26 years ago
Bruce Momjian	8a093d0ae3	Make number of args to a function configurable.	26 years ago
Tom Lane	166b5c1def	Another round of planner/optimizer work. This is just restructuring and ... code cleanup; no major improvements yet. However, EXPLAIN does produce more intuitive outputs for nested loops with indexscans now...	26 years ago
Bruce Momjian	4ae43c84c3	Add opid to selectivity function call.	26 years ago
Bruce Momjian	922e53e6ea	Enable pg_statistic cache use.	26 years ago
Bruce Momjian	fc955b14ea	Add system indexes to match all caches. ... 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.	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
Tom Lane	51db6455ea	Repair error noticed by Roberto Cornacchia: selectivity code ... was rejecting negative attnums as bogus, which of course they are not. Add code to get_attdisbursion to produce a useful value for OID attribute, since VACUUM does not store stats for system attributes. Also, repair bug that's been in eqjoinsel for a long time: it was taking the max of the two columns' disbursions, whereas it should use the min.	26 years ago
Tom Lane	d91baea025	Ooops ... I had left some test coding in selfuncs.c that ... failed on 'field < textconstant' ...	26 years ago
Tom Lane	14f84cd821	Store -1 in attdisbursion to signal 'no duplicates in column'. ... Centralize att_disbursion readout logic.	26 years ago
Tom Lane	8624ff7612	Further selectivity-estimation work. Speed up eqsel() ... (it should just call the given operator, not look up an = operator). Fix intltsel() so that all numeric data types are converted to double before trying to estimate where the given comparison value is in the known range of column values. intltsel() still needs work, or replacement, for non-numeric data types ... but for nonintegral numeric types it should now be delivering reasonable estimates.	27 years ago
Tom Lane	44878506d8	First step in fixing selectivity-estimation code. eqsel and ... neqsel now behave as per my suggestions in pghackers a few days ago. selectivity for < > <= >= should work OK for integral types as well, but still need work for nonintegral types. Since these routines have never actually executed before :-(, this may result in some significant changes in the optimizer's choices of execution plans. Let me know if you see any serious misbehavior. CAUTION: THESE CHANGES REQUIRE INITDB. pg_statistic table has changed.	27 years ago
Bruce Momjian	3406901a29	Move some system includes into c.h, and remove duplicates.	27 years ago

Tom Lane	d30c4b0562	Temporarily disable error checks for missing selectivity ... functions, in order to work around oversight in 6.5 release: rtree index functions haven't got any. Mea culpa ...	27 years ago
Tom Lane	81ced1e037	Generate a more specific error message when an operator used ... in an index doesn't have a restriction selectivity estimator.	27 years ago
Bruce Momjian	07842084fe	pgindent run over code.	27 years ago

Bruce Momjian	af74855a60	Renaming cleanup, no pgindent yet.	27 years ago
Bruce Momjian	7971539020	heap_fetch requires buffer pointer, must be released; heap_getnext ... 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;	27 years ago
