Before v7.2, you have no way to resolve this, however, from v7.2, you can return a cursor with PL/pgSQL, so I think you may resolve this problem by cursor. But I haven't tested it yet.

i think you declare 'return set of int' as the retunr type of the function, but i'm not sure if you can return a set of rows as a dataset from a function. i guess you could define a data type as a row and retunr a set of them but i'm only guessing as my knowledge /experience doesn't stretch that far i'm afraid ....

I am new to pgsql having worked with M$SQL for a while, my question would be if functions are the equivelent to Stored Procedures, how does one return a rowset, instead of a single typed variable? If this is the wrong group, my apologies and please point me to the correct one.
Thanks,
