Teodor Sigaev	9ee014fc89	Bloom index contrib module ... Module provides new access method. It is actually a simple Bloom filter implemented as pgsql's index. It could give some benefits on search with large number of columns. Module is a single way to test generic WAL interface committed earlier.

Tom Lane	d9b9289c83	Suppress compiler warning. ... Given the limited range of i, these shifts should not cause any problem, but that apparently doesn't stop some compilers from whining about them. David Rowley	10 years ago
Tom Lane	be44ed27b8	Improve index AMs' opclass validation procedures. ... The amvalidate functions added in commit 65c5fcd353 were on the crude side. Improve them in a few ways: * Perform signature checking for operators and support functions. * Apply more thorough checks for missing operators and functions, where possible. * Instead of reporting problems as ERRORs, report most problems as INFO messages and make the amvalidate function return FALSE. This allows more than one problem to be discovered per run. * Report object names rather than OIDs, and work a bit harder on making the messages understandable. Also, remove a few more opr_sanity regression test queries that are now superseded by the amvalidate checks.	10 years ago
Tom Lane	65c5fcd353	Restructure index access method API to hide most of it at the C level. ... This patch reduces pg_am to just two columns, a name and a handler function. All the data formerly obtained from pg_am is now provided in a C struct returned by the handler function. This is similar to the designs we've adopted for FDWs and tablesample methods. There are multiple advantages. For one, the index AM's support functions are now simple C functions, making them faster to call and much less error-prone, since the C compiler can now check function signatures. For another, this will make it far more practical to define index access methods in installable extensions. A disadvantage is that SQL-level code can no longer see attributes of index AMs; in particular, some of the crosschecks in the opr_sanity regression test are no longer possible from SQL. We've addressed that by adding a facility for the index AM to perform such checks instead. (Much more could be done in that line, but for now we're content if the amvalidate functions more or less replace what opr_sanity used to do.) We might also want to expose some sort of reporting functionality, but this patch doesn't do that. Alexander Korotkov, reviewed by Petr Jelínek, and rather heavily editorialized on by me.	10 years ago
