Yes I did. The warning line looks like:

jd@scratch:~/pgsql/src/bin/psql$ ./psql -U jd -h localhost postgres
psql 8.4devel
WARNING: Server version 8.2, psql version 8.4. psql features may not work.

Type: help for help. 


I did add tabs so the message would stand out more but that isn't
really any different than the old banner message.

The version is shown:

jd@scratch:~/pgsql/src/bin/psql$ ./psql -U jd -h localhost -p9000
postgres
psql 8.4devel

Type: help for help. 
postgres=# 

I left off server version because there doesn't seem to be a reason to
have it except if the server doesn't match. For example, Benjamin's
comment was:

--
To take a field example, I have one site where I run an 8.2 production
cluster, an 8.3 application testing cluster and my a personal 8.4devel
cluster for hacking postgres.

In such an environment, it's *very* useful to have instant feedback on
which server I've just connected to with psql.

Which this patch does supply.

Sincerely,

Joshua D. Drake
