How to restore PostgreSQL database

Question

I'm working in project with a CMS called tendenci using PostgreSQL (it is required) in Ubuntu, and I had to migrate from a Virtual Machine to the production server. But I faced a problems with migrating the database.

I used this command to extract data from VM:

pg_dump -Fc mydb > db.dump

but when I tried to import data to my server with this command

psql -d mydb --file=db.dump 

this error shows up

The input is a PostgreSQL custom-format dump.
Use the pg_restore command-line client to restore this dump to a database.

and when I use pg_restore command no errors show up, but the database doesn't get restored.

pg_restore -C -d mydb db.dump

Answer 1

To move the complete database cluster, including all users etc., use the following commands:

$ pg_dumpall >all-db.sql

and then on the target server initialize an new and emppty database cluster, start it, and then run

$ psql -f all-db.sql

Run the pg_dumpall and psql commands as the postgres user.
