Re: [GENERAL] pg_dump --compress error
I tried it and it ran without any error but my table wasn't created so problem is going on. compress level isn't important because when I controlled it gave me same results ( 5 or 9 ) Unfortunately, only plain-old dump works correctly while restoring. if command contains any compress option, it won't work any suggestion ? -- Yasin MALLI System Software Development Engineer yasinma...@gmail.com , yasinma...@yahoo.com On Mon, Aug 30, 2010 at 11:38 PM, Alban Hertroys dal...@solfertje.student.utwente.nl wrote: On 31 Aug 2010, at 8:17, yasin malli wrote: Don't reply to just me, include the list. if I took my dump file with 'pg_dump -Ft ' command, I would use 'pg_restore', but I take my dump file at plain-old format for compressing data ( tar format dump hasn't compress feature ) when I tried your suggestion, I take this error : pg_restore: [archiver] input file does not appear to be a valid archive Ah right, most people use --compress in combination with the custom format (-Fc).

I'm not real sure what you get if you specify it without that; maybe a compressed plain-text-script dump? If so, you'd have to pass it through gunzip and then to psql to do anything useful with it. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
