It may well be that for plperl and friends we can kick the problem off
to language-specific debuggers --- indeed, one of the first things we
need to do is look at those to see what we can avoid reinventing.
But what of plpgsql?

Also, any solution of this type probably requires that the person doing
debugging have database superuser access (in fact, be logged directly
into the server machine as the postgres user).  It'd be nice to have an
approach that could be used by non-superusers to debug their trusted-PL
functions.
