From: Robert Haas Date: Mon, 27 Mar 2017 15:00:09 +0000 (-0400) Subject: Tidy up the CREATE TABLE documentation for partitioning. X-Git-Tag: REL_10_BETA1~482 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4785e377f9c3189c06051ece7ebb112220f365f6;p=thirdparty%2Fpostgresql.git Tidy up the CREATE TABLE documentation for partitioning. Remove some tags that make this too "loud". Fix some typos.
