Export DB with PostgreSQL's PgAdmin-III

Question

How to export a Postgresql db into SQL that can be executed into other pgAdmin?

• Exporting as backup file, doesn\'t work when there\'s a difference

Answer 1

Export/Import with pg_dump and psql

1.Set PGPASSWORD

export PGPASSWORD='123123123';

2.Export DB with pg_dump

pg_dump -h <> -U <> <> > /opt/db.out 

/opt/db.out is dump path. You can specify of your own.

3.Then set again PGPASSWORD of you another host. If host is same or password is same then this is not required.

4.Import db at your another host

psql -h <> -U <> -d <> -f /opt/db.out

If username is different then find and replace with your local username in db.out file. And make sure on username is replaced and not data.

If you still want to use PGAdmin then see procedure below.
