Обсуждение: pgdump from 8.0.4 not valid for import into 8.1.0

? In pgAdminIII linked to 8.0.4 server did a backup of all databased.
Chose "plain" and saved to disk.
uninstalled 8.0.4
installed 8.1.0

create database in pgAdminIII v1.4
restore
---- reports as not a valid archive.

Obviously this is not what I expect.
Some older backups from a 7.4.? server on a Redhat machine will restore.

Please ? why is what I have done failed.

thanks

Richard

I'd guess it's expecting the "custom" archive format which lets you pick
and choose what to restore. Someone more knowledgable will pop up and
say for certain shortly.

You should be able to feed a "plain" backup to psql or to pg_restore though.

Thanks Richard. Backup as compressed worked.
