Hello,
I would like to allow a co-worker to perform a backup of a database, such that the backup is saved to the database server itself. One use case is that (s)he would like an extra backup of a database, just before an application update is deployed. The co-worker doesn't have shell access on the DB server (so no sudo option), and we would like to allow this to happen without having to involve a DBA.
Is it possible to call pg_dump (or equivalent action) through a procedure/function?
An alternative is continuous (aka PITR) backups using something like PgBackRest. Weekly full backups, incremental backups on the other six days, and WAL files that keep you up to date.
CHECKPOINT; and SELECT pg_switch_wal(); are all that's needed before she deploys the update.
