`\d` (describe) does not work unscoped or with a table name

[timsehn]

This is supposed to return a list of tables:

employees=> \d
ERROR:  syntax error at position 666 near 'nspname' (errno 1105) (sqlstate HY000)

This is supposed to describe said table.

employees=> \d employees
ERROR:  syntax error at position 158 near 'OPERATOR' (errno 1105) (sqlstate HY000)
