Column info without executing query - Mailing list pgsql-general

Hi List !

I would like to know if it is possible to find out the datatypes in the
resultset of a query or a set returning
function without actually executing them ?

I know there is something like that in MS SQL Server where you can use
the SET FMTONLY option and only
get the column information back from the query .

Would something like that be possible in postgres ?

Dan
