[PATCH] server_version_num should be GUC_REPORT - Mailing list pgsql-hackers

Hi all

While looking into client code that relies on parsing server_version
instead of checking server_version_num, I was surprised to discover that
server_version_num isn't sent to the client by the server as part of the
standard set of parameters reported post-auth.

The docs reflect this:

http://www.postgresql.org/docs/current/static/protocol-flow.html#PROTOCOL-ASYNC

The attached patch marks server_version_num GUC_REPORT and documents
that it's reported to the client automatically.
