Patch looks good. One minor issue:

greg=# \set WATCH_INTERVAL -1
invalid value "-1" for "WATCH_INTERVAL": must be greater than 0.00
greg=# \set WATCH_INTERVAL 0.00
greg=#

We should disallow 0 as the error message implies

Ah, nice catch, fixed in the attached along with a test for the minimum bound (ie zero).

I've long wanted to be able to set the default interval for \watch in psql since I almost never want a 2 second wait. 

Curious what other's personal defaults are? I usually use 1 second or 0.5 depending on things.

I rarely use anything higher than 0.5.
