Subject: configure: Allow adding a custom string to PG_VERSION
X-Git-Tag: REL9_4_BETA1~792
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=46328916eefc5f9eaf249518e96f68afcd35923b;p=postgresql

configure: Allow adding a custom string to PG_VERSION

This can be used to mark custom built binaries with an extra version
string such as a git describe identifier or distribution package release
version.
