Yeah. Anything that involves smashing all the fields to text is not
really an advance over (a) hstore or (b) using plperl or one of the
other weakly-typed PLs.
I think there's a fairly fundamental contradiction involved here.
One of the basic design attributes of plpgsql is that it's strongly
typed. Sometimes that's a blessing, and sometimes it's not, but
it's a fact. There really isn't a good way to deal with run-time
field selection while still maintaining strong typing. I do not
believe that the answer to that problem is "so let's break strong
typing". Rather, the answer is that if that's what you need, you
need to use a different tool. There's a reason we support multiple
PLs.
