From: Andres Freund Date: Tue, 22 Aug 2017 14:46:05 +0000 (-0700) Subject: Backpatch introduction of TupleDescAttr(tupdesc, i). X-Git-Tag: REL_10_BETA4~21 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d34a74dd064af959acd9040446925d9d53dff15b;p=postgresql Backpatch introduction of TupleDescAttr(tupdesc, i). 2cd70845240 / c6293249d change the way individual attributes in a TupleDesc are stored / accessed. To reduce the effort of making extensions compatible with postgresql 11, and to ease future backpatching, backpatch introduction of TupleDescAttr() to all releases. Do not backpatch change in storage, as that'd be a breaking change for existing and working extensions.
