What exactly is in your Program Files?

Karen> org.postgresql.util.PSQLException: ERROR: operator does not exist: text = character varying[]
Someone just asked this a few minutes ago on the IRC channel but left
without acknowledging my response; was that you?

character varying[] means _array of varchar_, of course you can't
compare an array directly against a scalar.
If you want to pass an array value as a parameter, you can't use IN (x), you
have to use = ANY (x) instead.
