Tom Lane	610dfa6d55	Combine index_info and find_secondary_indexes into a single routine that returns a list of RelOptInfos, eliminating the need for static state in index_info. That static state was a direct cause of coredumps; if anything decided to elog(ERROR) partway through an index_info search of pg_index, the next query would try to close a scan pointer that was pointing at no-longer-valid memory. Another example of the reasons to avoid static state variables...	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	49ed4dd779	Further work on planning of indexscans. Cleaned up interfaces to index_selectivity so that it can be handed an indexqual clause list rather than a bunch of assorted derivative data.	26 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

PostgreSQL Daemon	baef78d96b	Thank god for searchable mail archives. Patch by: wieck@sapserv.debis.de (Jan Wieck) One of the design rules of PostgreSQL is extensibility. And to follow this rule means (at least for me) that there should not only be a builtin PL. Instead I would prefer a defined interface for PL implemetations.	28 years ago

Vadim B. Mikheev	67712200f1	* Hack for non-functional btree npages estimation: * npages = index_pages * selectivity_of_1st_attr_clause(s)	29 years ago
Vadim B. Mikheev	fa2629b7ea	Fix (hack) IndexSelectivity(): use sum(npages)/((nkeys == 1) ? 1 : nkeys + 1) as expected index page estimation for multi-key quals - instead of sum(npages). In old code npages for x > 10 and x < 20 is twice as for x > 10 - cool ?	29 years ago
Marc G. Fournier	5dde558ce6	From: Dan McGuirk <mcguirk@indirect.com> Subject: [HACKERS] linux/alpha patches These patches lay the groundwork for a Linux/Alpha port. The port doesn't actually work unless you tweak the linker to put all the pointers in the first 32 bits of the address space, but it's at least a start. It implements the test-and-set instruction in Alpha assembly, and also fixes a lot of pointer-to-integer conversions, which is probably good anyway.	29 years ago
