I don't know much about date/time datatypes, but valuntil is of type
abstime, and you can set it to infinity:
alvh=# alter user alvh valid until 'infinity';
ALTER USER
alvh=# select usename, valuntil from pg_shadow where usename='alvh';usename | valuntil
---------+----------alvh | infinity
(1 row)
I see now that one can use this syntax to make a user valid forever,
though it is different than setting the value to NULL (as is when the
user hasn't got a validity defined). This should be mentioned in the
docs, I think.
