Backing up several tables using pg_dump -t

I'm having problem backing up several tables using pg_dump. When
selecting one table only with the '-t' option, it works just fine. When
I tried to include several tables, pg_dump fails with error that the
tables specified don't exist. Can you show me an example of backing up
several tables using pg_dump.

Thanks in advance,

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.

I'd just warp pg_dump in a little (shell-)script or dump all tables and
pass pg_restore a TOC list (-L option) of objects I want.

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.]
