Teodor Sigaev	d4c6da1527	Allow GIN's extractQuery method to signal that nothing can satisfy the query. ... In this case extractQuery should returns -1 as nentries. This changes prototype of extractQuery method to use int32* instead of uint32* for nentries argument. Based on that gincostestimate may see two corner cases: nothing will be found or seqscan should be used. Per proposal at http://archives.postgresql.org/pgsql-hackers/2007-01/msg01581.php PS tsearch_core patch should be sightly modified to support changes, but I'm waiting a verdict about reviewing of tsearch_core patch.	19 years ago

Teodor Sigaev	234163649e	GIN improvements ... - Replace sorted array of entries in maintenance_work_mem to binary tree, this should improve create performance. - More precisely calculate allocated memory, eliminate leaks with user-defined extractValue() - Improve wordings in tsearch2	20 years ago
Tom Lane	3fdeb189e9	Clean up code associated with updating pg_class statistics columns ... (relpages/reltuples). To do this, create formal support in heapam.c for "overwrite" tuple updates (including xlog replay capability) and use that instead of the ad-hoc overwrites we'd been using in VACUUM and CREATE INDEX. Take the responsibility for updating stats during CREATE INDEX out of the individual index AMs, and do it where it belongs, in catalog/index.c. Aside from being more modular, this avoids having to update the same tuple twice in some paths through CREATE INDEX. It's probably not measurably faster, but for sure it's a lot cleaner than before.	20 years ago
