On: Don't use MongoDB

[phaylon]

You could try `time psql < alter-statement.sql`. I know, it'd not really be useful as it measures lots of overhead. But if it's fast on that, it's fast during an active session.

I could have turned on timing too (\timing in psql). All I know is it returned within one sec. Oh well, next time, I suppose.
