I updated the patch.  This gives psql three output displays on startup:

full match:

	Welcome to psql 8.1beta1, the PostgreSQL interactive terminal.

major match:

	Welcome to psql, the PostgreSQL interactive terminal.
	psql version 8.19, server version 8.1

and non-major match:
	
	WARNING:  You are connected to a server with major version 8.1,
	but your psql client is major version 8.2.  Informational backslash
	commands, like \d, might not work properly.
	
	Welcome to psql, the PostgreSQL interactive terminal.
	psql version 8.29, server version 8.1

Patch attached.
