The fuller description of what happens is here:
http://www.postgresql.org/docs/9.4/interactive/app-psql.html
\pset [ option [ value ] ]
tuples_only (or t)
If value is specified it must be either on or off which will enable
or disable tuples-only mode. If value is omitted the command toggles
between regular and tuples-only output. Regular output includes extra
information such as column headers, titles, and various footers. In
tuples-only mode, only actual table data is shown.
