Обсуждение: Generic/Ad-Hoc Select Function
I am new to Postgresql and was wondering if it is possible to create an ad-hoc select query function, where the table name, and the where clause were passed to the function and it returned a result set for the table?
Thanks
Roy

Yes. You should be able to do this in most of not all of the PLs. A good start is to read this: http://developer.postgresql.org/docs/postgres/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN
