Makes sense.

I'm still going to try to get notification payloads done for 8.3, which
will remove any requirement of catalog support and do it all in shared
memory.

Should we perhaps support a variant that allows a string as opposed to
an identifier as the name?

  LISTEN
'really_really_really_really_really_really_really_really_really_really_really_really_long_name'
;

Or is that just silly? ;-)
