Обсуждение: Dragging and dropping tables between databases

Okay, maybe not that simple, but is there a way to transfer a table
easily between two databases?

The easiest way I can think of is to back-up the table in an sql file
and then run the sql file in the other database.  Is that the easiest?

I guess I should sign this, Homer Simpson.

Thanks,

John Gage

Yeah, or:

pg_dump | psql

with proper parameters.

You mean like a one-off copy?

pretty-much  pg-dump has other non-sql formats  but at the end of the
day dumping to SQL (and compressing with something if there's a
significant physical distance to cover) is about as good as it gets.


But if you want a read-only copy that's kept mostly up-to-date there are
other solutions.
