When pg_autovacuum checks these static databases it is triggering the warning: "non standard use of \\ in a string literal at character 128 or character 355" depending upon which database it is checking. This is a tad hard to believe, as the 8.1 version of pg_autovacuum doesn't generate any commands that need to be parsed. Nor can I reproduce this while testing. Can you provide more context? regards, tom lane
