I'm pretty uninspired by this choice of syntax. Logical replication
seems to have added a whole bunch of syntax that involves prefixing
words with "no". In various places, there's NODROP, NOREFRESH, NOCOPY
DATA, NOCONNECT, and NOPUBLISH. But "NO" is not an English prefix,
and there's no precedent of which I'm aware for such SQL syntax. In
most places, we've chosen to name the option and then the user set it
to "on" or "off". So for example you type EXPLAIN (ANALYZE, TIMING
OFF) or EXPLAIN (ANALYZE, TIMING FALSE), not EXPLAIN (ANALYZE,
NOTIMING). I think most of the logical replication stuff could have
been done this way pretty easily, but for some reason it picked a
completely different approach.
