I found pg_prog.prorettype in the system catalogs , is it possible to
use that to find the resultset datatypes of a
set returning function ?
Anyway , maybe the odbc driver will work by using SQLDescribecol()
without executing it ?!
I found something in the archives where someone suggests that it has
worked before at least
