From 0fe77d7283160fc9dc5b5cacd1a70502835350e3 Mon Sep 17 00:00:00 2001 From: Bruce Momjian Date: Thu, 20 Mar 2003 19:00:01 +0000 Subject: [PATCH] The documentation for SELECT is incorrect in a sense: the syntax for a join is defined as: from_item [ NATURAL ] join_type from_item [ ON join_condition | USING ( join_column_list ) ] However, if the join_type is an INNER or OUTER join, an ON, USING, or NATURAL clause *must* be specified (it's not optional, as that segment of the docs suggest). I'm not exactly sure what the best way to fix this is, so I've attached a patch adding a FIXME comment to the relevant section of the SGML. If anyone has any ideas on the proper way to outline join syntax, please speak up.
