Обсуждение: Pg_dump
1) I want to take a pg_dump of only few tables /usr/local/pgsql/bin/pg_dump -t [table_name] database_name > file.out allows me only to take dump of single table. Is there a way to take dump of more than one specific tables. 2) Does pg_dump allow me to take dump of a table so that only some records are included in the dump (Some thing like specifying a QUERY in the pg_dump) -- Best, Gourish Singbal

No, it's not in 8.0 either; you still need a separate pg_dump run for each
table.

Benig able to exclude tables from dump's would be useful as well.

There was some discussion about doing this kind of thing about 6 months ago (shortly before beta). I appearantly misremembered the end result of the discussion, but you should be able to find it in the archives. > > Greg > > -----Original Message----- > From: Tom Lane [mailto:tgl@sss.pgh.pa.us] > Sent: Sunday, December 26, 2004 6:34 PM > To: Bruno Wolff III > Cc: Gourish Singbal; pgsql-admin@postgresql.org > Subject: Re: [ADMIN] Pg_dump > > > Bruno Wolff III <bruno@wolff.to> writes: > > Gourish Singbal <gourish@gmail.com> wrote: > >> allows me only to take dump of single table.

Thanks i will try to find the answer in the archives, Also will having a saperate schema for a set of tables help me in taking pg_dump only of specific tables. is it possible to create schema for already existing postgresql database tables ?. Also how do i know is any tables need recovery... like in oracle we come to know from a view called as v$recovery_log. is some thing like is this possible in postgres.
