I like that idea.  Here is a minimal patch that allows you to put

\set WELCOME_MESSAGE none

or

\set WELCOME_MESSAGE terse

into .psqlrc.  The latter keeps the version information but omits the 
information about the backslash commands.  I didn't change any of the message 
wordings.  Simon's argument that screenshots and HOWTOs would need to be 
updated is not invalid.

I think everyone will find a mode they like here.
