Thread: sql dump
Hi all, Is it possible to perform an SQL Dump without using pg_dump? I have a special case situation wherein my application has access to a remotely-hosted PG (8.3) database, but does not have access to its admin tools. (There's a longer backstory here that I'm happy to explain if necessary.) I'm looking for an efficient way to dump all the data in the DB without having to SELECT * on each table. Thanks in advance! Scott

I don't think so. Are you in a position to run pg_dump locally to the application, using the -h parameter to connect to the remote DB? You really are better off to use pg_dump if you can at all, since it looks after FK dependencies between tables, permissions, etc. Ray. -- Raymond O'Donnell :: Galway :: Ireland rod@iol.ie

COPY might be of use: http://www.postgresql.org/docs/8.3/interactive/sql-copy.html though you will have to specify each table of course. Ian Barwick

No, but there may be more options for using pg_dump than you have looked at. One example would be to use pg_dump on one with an SSH tunnel to the other one's local PostgreSQL port (5432 by default, but check which yours is). For example: ssh -fNR 5432:localhost:5555 postgres@your.host.dom would let you connect to localhost:5555 with pg_dump and any other PostgreSQL tools.

Maybe with a stored procedure that reads metadata plus data and spits everything out in sql-form to stdout somehow. plperlmight be a good language choice. -----Original Message----- From: pgsql-general-owner@postgresql.org [mailto:pgsql-general-owner@postgresql.org] On Behalf Of Scott Frankel Sent: Monday, July 26, 2010 11:59 AM To: PostgreSQL List Subject: [GENERAL] sql dump Hi all, Is it possible to perform an SQL Dump without using pg_dump?

Thanks for all the suggestions. COPY may work for my purposes. The SSH tunnel option for using pg_dump is very interesting. Thanks!
