(This will usually mean the environment variables <envar>PGDATABASE</envar>, <option>-h</option>, <option>-p</option>, and <option>-U</option> respectively.
If an argument is found that does not belong to any option it will be interpreted
as database name as well. Not all these options are required, defaults do apply.
If you omit the host name psql will connect via domain sockets to a server on the
local host. The default port number is compile-time determined. Since the database
server uses the same default, chances are you don't have to specify the port in most
settings. The default user name is your Unix username, the same with the database.
Note that you can't just connect to any database under any username. Your database
administrator should have informed you about your access rights. To save you some typing
you can also set the environment variables <envar>PGDATABASE</envar>,
<envar>PGHOST</envar>, <envar>PGPORT</envar>, <envar>PGUSER</envar>, <envar>PGHOST</envar>, <envar>PGPORT</envar>, <envar>PGUSER</envar>,
respectively, if they are set. Otherwise the default host is the local host respectively to appropriate values.
via Unix domain sockets, the default port is decided at compile time,
the default user is the system user name, and the default database is
the one with the same name as the user.)
