Heikki Linnakangas 7ac4a389a7 Don't create "holes" in BufFiles, in the new logtape code. ... The "Simplify tape block format" commit ignored the rule that blocks returned by ltsGetFreeBlock() must be written out in the same order, at least in the first write pass. To fix, relax that requirement, by making ltsWriteBlock() to detect if it's about to create a "hole" in the underlying BufFile, and fill it with zeros instead. Reported, analysed, and reviewed by Peter Geoghegan. Discussion: https://www.postgresql.org/message-id/CAM3SWZRWdNtkhiG0GyiX_1mUAypiK3dV6-6542pYe2iEL-foTA@mail.gmail.com		2017-02-01 12:17:38 +02:00
