Does that actually work on your system? On the system I tested it
sends screen control garbage to the pipe. Aside from that, "watch"
isn't a standard command -- on one of my systems (FreeBSD) I get this:
watch: fatal: cannot open snoop device
On another (Solaris) I get this:
watch: Command not found.
Additionally, periodically doing "SELECT * FROM pg_stat_activity"
isn't a reliable way to see *all* queries, as you'll miss queries
that happened between your SELECTs. It's also wasteful of resources,
especially if you start a new session for each query.
