Thanks Rajesh.

Is this on TODO list? I think it's beneficial to be able to backup (or
oracle term, export) several tables (NOT only ONE) and restore (import)
back to another database for instance from a production DB to a
development or staging to prod, etc..)  [This is doable in Oracle too
via the export/import utilities.]

man pg_dump seems to say it is not possible

       -t table

       --table=table
              Dump  data for table only. It is possible for there to be
multi-
              ple tables with the same name in different schemas; if
that  is
              the  case,  all  matching  tables  will  be dumped.
Specify both
              --schema and --table to select just one table.

              Note: In this mode, pg_dump makes no attempt to dump  any
other
              database objects that the selected table may depend upon.
There-
              fore, there is no guarantee that the results of  a
single-table
              dump  can  be  successfully  restored by themselves into a
clean
              database.
