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; > > Is there a way to use the integer only generate_series in 8.3 to generate > dates by typecasting to/from integers? -- Adrian Klaver adrian.kla...@gmail.com -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
