From 04912899e792094ed00766b99b6c604cadf9edf7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add new variable "server_version_num", which is almost the
same as "server_version" but uses the handy PG_VERSION_NUM which allows apps
to do things like if ($version >= 80200) without having to parse apart the
value of server_version themselves.
