Import SQL dump into PostgreSQL database

Question

We are switching hosts and the old one provided a SQL dump of the PostgreSQL database of our site.

Now, I\'m trying to set this up on a local WAMP server to test thi

Answer 1

Postgresql12

from sql file: pg_restore -d database < file.sql

from custom format file: pg_restore -Fc database < file.dump

Answer 2

You can do it in pgadmin3. Drop the schema(s) that your dump contains. Then right-click on the database and choose Restore. Then you can browse for the dump file.

Answer 3

I noticed that many examples are overcomplicated for localhost where just postgres user without password exist in many cases:

psql -d db_name -f dump.sql

Answer 4

Follow the steps:

1. Go psql shell
2. \c db_name
3. \i path_of_dump [eg:-C:/db_name.pgsql]

Answer 5

That worked for me:

sudo -u postgres psql db_name < 'file_path'

Answer 6

psql databasename < data_base_dump

That's the command you are looking for.

Beware: databasename must be created before importing. Have a look at the PostgreSQL Docs Chapter 23. Backup and Restore.
