Resynch database sequences after backup restore

[htmfilho]

Describe the bug

The implemented database backup is based on SQL scripts. It allows recovering the database without the application being up and running. However, it makes sequences get out of synch, causing issues with inserting new records due to primary-key conflicts.

To Reproduce

Steps to reproduce the behavior:

1. Generate a backup file
2. Create a new database and restore the backup
3. Document a new table

Expected behavior

We expect sequences to be in sync with primary keys.

[htmfilho]

Implemented a solution that works in PostgreSQL, but not in H2. When we try to insert a new record and a primary key conflict happens, we increment the sequence in a recursive call until it doesn't conflict with the primary key anymore.

A solution for H2 is yet to be found. We may need to create the sequences manually or change the backup file from SQL to JSON.
