Thread: duplicate table in two databases

I use postgres 7.2.1 (debian woody) and PHP.

I've two databases (foo and bar for example) with the same table (ie. 
stamps).

It's possible with a single query transfer the data from the stamps 
table in db foo to the stamps table in db bar?

Or I need a row by row copy? Or maybe a dump on temp file?

(with one db and two tables with the same record I can use INSERT INTO 
foo SELECT * FROM bar).

Thanks.

You might want to look in the contrib/ folder of the source distribution 
(or the equivalent in your packaged installation for "dblink". Haven't 
used it myself, but it can certainly do what you want here.
