huh -- I didn't know that! Testing it out, all JOIN types imply LATERAL if the function call is tlist SRF style (which is pretty werid IMO) I tend to avoid optional words (with the important exception of AS for column list renames) but I think it's a good idea to disclose LATERAL in this case. It's a big clue to the reader what is going on and the expanded form: SELECT foo.* FROM foo CROSS JOIN LATERAL (SELECT a,b FROM func(foo.bar)) q; ... requires LATERAL to be explicitly stated. This form is more general since it can be cleanly used when func() returns more than one column. merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
