psql is the PostgreSQL interactive terminal client, a command-line based interface to PostgreSQL databases. Although many users will deem psql to be the most rudimentary interface, it is a terrific way to browse the Unison schema and experiment with queries rapidly. psql is part of the PostgreSQL distribution; binaries and source code are available from http://www.postgresql.org/.
Unison is available to the public at host
unison, as user
PUBLIC. No password is
required. (The default PostgreSQL port,
5432, is used and is not
typically required.) A typical session looks like this:
eg$ psql -h unison-db.org -U PUBLIC -d unison Welcome to psql 8.0.3, 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 unison=>
From now on, I'll use assume you're already connected to Unison and will use
unison=> as the prompt.
