Kevin Grittner	a343e223a5	Revert no-op changes to BufferGetPage() ... The reverted changes were intended to force a choice of whether any newly-added BufferGetPage() calls needed to be accompanied by a test of the snapshot age, to support the "snapshot too old" feature. Such an accompanying test is needed in about 7% of the cases, where the page is being used as part of a scan rather than positioning for other purposes (such as DML or vacuuming). The additional effort required for back-patching, and the doubt whether the intended benefit would really be there, have indicated it is best just to rely on developers to do the right thing based on comments and existing usage, as we do with many other conventions. This change should have little or no effect on generated executable code. Motivated by the back-patching pain of Tom Lane and Robert Haas	10 years ago
Tom Lane	5713f03973	Improve API of GenericXLogRegister(). ... Rename this function to GenericXLogRegisterBuffer() to make it clearer what it does, and leave room for other sorts of "register" actions in future. Also, replace its "bool isNew" argument with an integer flags argument, so as to allow adding more flags in future without an API break. Alexander Korotkov, adjusted slightly by me	10 years ago
Kevin Grittner	8b65cf4c5e	Modify BufferGetPage() to prepare for "snapshot too old" feature ... This patch is a no-op patch which is intended to reduce the chances of failures of omission once the functional part of the "snapshot too old" patch goes in. It adds parameters for snapshot, relation, and an enum to specify whether the snapshot age check needs to be done for the page at this point. This initial patch passes NULL for the first two new parameters and BGP_NO_SNAPSHOT_TEST for the third. The follow-on patch will change the places where the test needs to be made.	10 years ago

Teodor Sigaev	e9e441c9fa	Prevent mark as deleted and as 'has free space' page in bloom module ... Vacuum might put page into list of pages with some free space and mark as deleted at the same time.	10 years ago
Teodor Sigaev	80afb62db0	Fixes in bloom contrib module ... Looking at result of buildfarm member jaguarundi it seems to me that BloomOptions isn't inited sometime, but I don't see yet how it's possible. Nevertheless, check of signature length's is missed, so, add a limit of it. Also add missed GenericXLogAbort() in case of already deleted page in vacuum + minor code refactoring.	10 years ago
Teodor Sigaev	27f3bbfad4	Fixes in bloom contrib module missed during review ... - macroses llike (var & FLAG) are changed to ((var & FLAG) != 0) - do not copy uninitialized part of notFullPage array to page	10 years ago
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.
