Hello there!

is there any way to create filter function?
i.e. function which will be accepting and returning row sets, like

select foo(t) from (select blah from tab) t;
something like this.

contrib/tablefunc seems not accepting a row set.

also, not related to above, i've typed query:

term2=>select * from tab where tab=1;
ERROR:  exprType: Do not know how to get type for 711 node

i know that query is wrong, but may be there must be more understandable error
message?

regards,
