In 8.3 I get: > > ERROR: set-valued function called in context that cannot accept a set > CONTEXT: PL/pgSQL function "date_range" line 4 at RETURN NEXT As to why it works in 8.4 vs 8.3 http://www.postgresql.org/docs/8.4/interactive/release-8-4.html "Support set-returning functions in SELECT result lists even for functions that return their result via a tuplestore (Tom) In particular, this means that functions written in PL/pgSQL and other PL languages can now be called this way.' In 8.3- I believe you could only call it as SELECT * from date_range (asdate, afdate)::date AS asdate; I don't think you can have that cast there when it is in the from-clause.
That was a cut and paste error on my part, I just copied that line from the original query.
