Subject: Add CHECK_FOR_INTERRUPTS while restoring changes during decoding.
X-Git-Tag: REL_14_6~14
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=36fc013fabd94f159553973f55afecc6cd115d60;p=postgresql.git

Add CHECK_FOR_INTERRUPTS while restoring changes during decoding.

Previously in commit 42681dffaf, we added CFI during decoding changes but
missed another similar case that can happen while restoring changes
spilled to disk back into memory in a loop.
