From e8fe426baa9c242d8dbd4eab1d963e952c9172f4 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 21 Sep 2018 15:58:37 -0400 Subject: [PATCH] Fix bogus tab-completion rule for CREATE PUBLICATION. You can't use "FOR TABLE" as a single Matches argument, because readline will consider that input to be two words not one. It's necessary to make the pattern contain two arguments. The case accidentally worked anyway because the words_after_create test fired ... but only for the first such table name. Noted by Edmund Horner, though this isn't exactly his proposed fix. Backpatch to v10 where the faulty code came in.
