Tom Lane 7fc7a7c4d0 Fix a violation of WAL coding rules in the recent patch to include an ... "all tuples visible" flag in heap page headers. The flag update *must* be applied before calling XLogInsert, but heap_update and the tuple moving routines in VACUUM FULL were ignoring this rule. A crash and replay could therefore leave the flag incorrectly set, causing rows to appear visible in seqscans when they should not be. This might explain recent reports of data corruption from Jeff Ross and others. In passing, do a bit of editorialization on comments in visibilitymap.c.		2009-08-24 02:18:32 +00:00
