This patch adds \watch to psql. It is much like the unix equivalent,
defaulting to every 2 seconds, and allowing you optionally specify a number
of seconds.
I will add this to the commit fest app.
Thanks,
Will Leinweber
Example:
psql (9.3devel, server 9.1.4)
Type "help" for help.
will=# \watch select now();
