Hi!
create table foo (
id int4 primary key,
....
);create function bar returns setof int4 langauge 'C' as '...' immutable strict ;
So query: select foo.* from foo, bar() as b where foo.id=b;
Function foo() always returns ordered values and after first call it knows exact number of results. It seems to me this information may be helpful for query optimizer, so, is there way to say it to optimizer?
