Subject: Handle XLOG_OVERWRITE_CONTRECORD in DecodeXLogOp
X-Git-Tag: REL_10_19~11
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=656312c2ac328aa8af20b4c5f0fab1f7f7202b2f;p=postgresql.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.
