$ ~/version82/bin/psql -p 5581 regression
Welcome to psql 8.2.0 (server 8.1.5), the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

WARNING:  You are connected to a server with major version 8.1,
but your psql client is major version 8.2.  Some backslash commands,
such as \d, might not work properly.
