What exactly is in your Program Files?

PostgreSQL which has folder named 10 and then open up you will get to see bin folder, data folder, script folder ....

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.

Is Any (x) this format applies only to Postgresql ? and x is subject_name the column name ?
