Strange, this works: select * from users where last_visit > now() + 7; -- last_visit is nullable, of type timestamp
But this doesn't select * from users where last_visit + 7 > now(); ERROR: Unable to convert null timestamp to date --
yes,there are users where last_visit IS NULL
BTW, this works too: select null+1; -- obviously returns NULL
System is FreeBSD 4.1, PgSQL 7.0.2
Anyone got a clue?
