Question

PostgreSQL

Lamersky question, but reading the manuals does not form a complete picture of how to do it right.
Given: postgres, database, a separate user to access this database with a password.
Task: to completely reroll the database dump.
How to do it on behalf of this user?

Answer 1

pg_dump + pg_restore/psql
pg_basebackup.
It all depends on the amount of data, server, access rules, task, etc.
