Building queries this way is tedious & error prone; that's just the way it is.

Put the command into a variable, then raise a notice with that variable, then execute it. That way, when you get a
failure,you just copy the failed SQL from the notice into an editor, tweak it until it works, then adjust your code
accordinglyto produce the corrected query.
