My idea is to put the information in a place where it is accessible,
but not obtrusive. version() seemed to be the only place for that
(server_version is just the short version), and it already has the
compiler version, so it fits, I think.

Exactly.
Added as https://commitfest.postgresql.org/16/1418/ now.
If people think it's worth it (windows?), I'll add a configure
--switch, otherwise with just reading from $VENDOR_VERSION, it's a
one-liner.
