|It seems I can do this from any higher level language, but it drives me

|Postgres...
Yes, semms very like this can't be done in just sql but needs a higher level
lng.
Actually Postgres provides such higher languages. Try including PL/Python
PL/perl or PL/tk. Fom there you are able to query all the metadata of the
wanted tables so that a adequate SQL-string can be generated.
In case of sourcecode, you find theses languages in the contrib dir

|Thanks for any thoughts you might have...
