From 253b3f6760e850945a91e2d872eab3b2802ffca2 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Mon, 12 Nov 2018 14:34:28 +0100 Subject: [PATCH] doc: Small run-time pruning doc fix A note in ddl.sgml used to mention that run-time pruning was only implemented for Append. When we got MergeAppend support, this was updated to mention that MergeAppend is supported too. This is slightly weird as it's not all that obvious what exactly isn't supported when we mention: Both of these behaviors are likely to be changed in a future release of PostgreSQL. This patch updates this to mention that ModifyTable is unsupported, which makes the above fragment make sense again.
