From 5b286cae3cc1c43d6eedf6cf1181d41f653c6a93 Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Tue, 22 Aug 2017 07:46:05 -0700 Subject: [PATCH] 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.
