Quoting of psql \d output

psql \d always double-quotes table names:

          Table "public.xx"
     Column |  Type   | Modifiers
    --------+---------+-----------
     y      | integer |
    Indexes:
        "ii" btree (y)


With this patch, double-quotes are not used when not required:

    test=> \d xx
           Table public.xx
     Column |  Type   | Modifiers
    --------+---------+-----------
     y      | integer |
    Indexes:
        ii btree (y)


but does in this case:

    test=> \d "xx y"
         Table public."xx y"
     Column |  Type   | Modifiers
    --------+---------+-----------
     y      | integer |
    Indexes:
        vv btree (y)

This patch uses pg_dump fmtId() to double-quote only when necessary.
