Tom Lane	a1fd650d2b	Fix contrib/pageinspect to not create an ABI breakage between 8.3 and 8.4. ... The original implementation of the 3-argument form of get_raw_page() risked core dumps if the 8.3 SQL function definition was mistakenly used with the 8.4 module, which is entirely likely after a dump-and-reload upgrade. To protect 8.4 beta testers against upgrade problems, add a check on PG_NARGS. In passing, fix missed additions to the uninstall script, and polish the docs a trifle.	17 years ago
Heikki Linnakangas	5f853c6556	Use fork names instead of numbers in the file names for additional ... relation forks. While the file names are not visible to users, for those that do peek into the data directory, it's nice to have more descriptive names. Per Greg Stark's suggestion.	18 years ago
Heikki Linnakangas	15c121b3ed	Rewrite the FSM. Instead of relying on a fixed-size shared memory segment, the ... free space information is stored in a dedicated FSM relation fork, with each relation (except for hash indexes; they don't use FSM). This eliminates the max_fsm_relations and max_fsm_pages GUC options; remove any trace of them from the backend, initdb, and documentation. Rewrite contrib/pg_freespacemap to match the new FSM implementation. Also introduce a new variant of the get_raw_page(regclass, int4, int4) function in contrib/pageinspect that let's you to return pages from any relation fork, and a new fsm_page_contents() function to inspect the new FSM pages.	18 years ago

Tom Lane	cc59049daf	Improve handling of prune/no-prune decisions by storing a page's oldest ... unpruned XMAX in its header. At the cost of 4 bytes per page, this keeps us from performing heap_page_prune when there's no chance of pruning anything. Seems to be necessary per Heikki's preliminary performance testing.	19 years ago
