Subject: Have pg_receivexlog always send an invalid log position in status messages
X-Git-Tag: REL9_2_BETA1~444
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d7ea9193d18d29bea82b30604cdd087e90c5ee27;p=postgresql

Have pg_receivexlog always send an invalid log position in status messages

This prevents pg_basebackup and pg_receivexlog from becoming a synchronous
standby in case 'write' is used for synchronous_commit.
