This bit seems a bit random:
# WAL segment, this is enough to guarantee that the history file was
# archived.
my $archive_wait_query =
- "SELECT '$walfile_to_be_archived' <= last_archived_wal FROM pg_stat_archiver;";
+ "SELECT coalesce('$walfile_to_be_archived' <= last_archived_wal, false) " .
+ "FROM pg_stat_archiver";
$node_standby->poll_query_until('postgres', $archive_wait_query)
or die "Timed out while waiting for WAL segment to be archived";
my $last_archived_wal_file = $walfile_to_be_archived;
I wonder whether that is a workaround for the poll_query_until bug
I proposed to fix at [1].
