Um, did you read the banner?

$ ~/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.

regression=#
