# VOSpace File Catalog (database)

**⚠ Work in progress! ⚠**

This repository defines the VOSpace database structure.

It consists in a PostgreSQL database with the [ltree](https://www.postgresql.org/docs/12/ltree.html) extension. SQL files are named starting with a number because they are put in a Docker image where they have to be executed in order.

## Dump and restore

To restore the file catalog from a dump it is necessary to drop the generated columns and regenerate them after the import. This can be done using the restore_db.sh script located in the dump_and_restore folder of this repository.

To obtain a data only dump of the database use the following command:

    pg_dump -h <hostname> -U postgres --data-only --format=tar vospace_testdb > mydump.tar

Then you can use the restore script in the following way:

    ./restore_db.sh -U postgres -h 127.0.0.1 -p 5432 -d vospace_testdb mydump.tar
