X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=2d4617126f6d708c5777b378d9ef282fb2c08930;p=users%2Fbernd%2Fpostgres.git

Document COLLATE option in CREATE TYPE reference page.

Curiously, it was already documented in ALTER TYPE ADD ATTRIBUTE, but
not here.
