Обсуждение: Restore after using pg_dumpall
Hallo,
between
pg_dumpall > alldb.sql (store)
and
psql –f alldb.sql postgres (restore)
is it necessary to drop existing objects (for example roles, …) ?
Any help is appreciated.

According above command,you are taking all databases dump in plain text format which are available in PostgreSQL cluster running on 5432 port number.
and
psql –f alldb.sql postgres (restore)
is it necessary to drop existing objects (for example roles, …) ?
According to above command,Restoring plain text dumpfile into same PostgreSQL cluster running on 5432 port number.
If my assumptions are correct then you should drop existing database objects.

I think it is not necessary. pg_dumpall supports dumping of the entire contents of a database cluster, It backs up each database in a given cluster, and also *preserves cluster-wide data such as role and tablespace definition*s. hence if you want to take backup for entire cluster then you can directly use pg_dumpall. or if you have any specific need then you can use pg_dump and manually preserve/delete other database objects . ----- Greetings, Samrat Revagade, NTT-DATA-OSS Center (Pune) -- View this message in context: http://postgresql.1045698.n5.nabble.com/Restore-after-using-pg-dumpall-tp5765452p5765716.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com.
