From 76f412ab310554acb970a0b73c8d1f37f35548c6 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 17 Sep 2020 16:17:27 -0400 Subject: Remove factorial operators, leaving only the factorial() function. The "!" operator is our only built-in postfix operator. Remove it, on the way to removal of grammar support for postfix operators. There is also a "!!" prefix operator, but since it's been marked deprecated for most of its existence, we might as well remove it too. Also zap the SQL alias function numeric_fac(), which seems to have equally little reason to live.
