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

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
