From a6536067095637a885e6d18cb8e0c971922fa662 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 29 May 2017 15:19:07 -0400 Subject: [PATCH] Allow NumericOnly to be "+ FCONST". The NumericOnly grammar production accepted ICONST, + ICONST, - ICONST, FCONST, and - FCONST, but for some reason not + FCONST. This led to strange inconsistencies like regression=# set random_page_cost = +4; SET regression=# set random_page_cost = 4000000000; SET regression=# set random_page_cost = +4000000000; ERROR: syntax error at or near "4000000000" (because 4000000000 is too large to be an ICONST). While there's no actual functional reason to need to write a "+", if we allow it for integers it seems like we should allow it for numerics too. It's been like that forever, so back-patch to all supported branches.
