plpgsql is not designed for that sort of thing; despite the existence of
"record" variables, it's really a strongly typed language and doesn't
cope well with fields of variable data types.  Consider using one of the
other PLs instead (plperl, plpython, etc depending on which language you
like best).  Most of them can handle this easily.
