Hi all,
I am trying to backup a large table with about 6 million rows. I want to
export the data from the table and be able to import it into another table
on a different database server (from pgsql 8.1 to 8.2). I need to export the
data through SQL query 'cause I want to do a gradual backup.

Thanks for quick response but pg_dump does not allow me to dump from a
SQL SELECT query which is what I wanna do.

Thanks all. The COPY command seems to do the work.
One more thing, say I want the data dumped on a remote machine rather than
on the current machine, how would I do that without having to first dump it
on the local machine then uploading to the remote machine?

If I wanted to use that with a command like COPY (SELECT * FROM country
WHERE country_name LIKE 'A%') TO 'filename'; do I specify the file
location for the remote machine as the filename or do I specify the
location for local machine?
And what if the psql clients are different (local: 8.1.5
Local file systems, and the user postgres needs write-access. I'm using
/tmp/... for such.
And yes: COPY from a select works only for 8.2 up, not for 8.1. Create a
table via 'create table as select ...' and COPY this table.
I'm trying to avoid exporting to the local machine before
