Great, thanks!

Yes, for whole tables (even sets of tables) "pg_dump --table=" is good at that. Even better, you can run the 9.6 pg_dump against the 8.3 database and get parallelism with "--jobs".

Ron, thanksagain. In case if I need to migrate the entire tables, I should be able to use pg_dump and pg_restore for certain tables, even between different versions, right? In case if I need to migrate from 8 to 9?
Thanks
(8.3? That's even older than what we just migrated from!!!)
No. Make some views (I'd probably make them "month-sized"), COPY each view from the source db to a file, and then COPY each file to it's relevant target table.
You should also think about a program named pg_bulkload.

Thank you Ron! What if dev environment is on 9.6, but prod is on version 8.3? Will posgtres_fdw still be the right option?

Hello psql friends,
We need to migrate only 6 months worth of data from one instance to another. What would be the easiest way to do it? In Oracle, I would set up dblink. What about postgresql?
