Subject: Handle XLOG_OVERWRITE_CONTRECORD in DecodeXLogOp
X-Git-Tag: REL_12_9~11
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=da782bc9341ca3ebeab1ec214f2610c4778234c2;p=thirdparty%2Fpostgresql.git

Handle XLOG_OVERWRITE_CONTRECORD in DecodeXLogOp

Failing to do so results in inability of logical decoding to process the
WAL stream.  Handle it by doing nothing.

Backpatch all the way back.
