Subject: Fix incorrect markup in documentation of window frame clauses.
X-Git-Tag: REL9_2_11~43
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=993674e80e511ac0c22a55c3261ce9760431cedc;p=postgresql

Fix incorrect markup in documentation of window frame clauses.

You're required to write either RANGE or ROWS to start a frame clause,
but the documentation incorrectly implied this is optional.  Noted by
David Johnston.
