Use the backup database connection while restoring timeouts
requested to merge 422163-pg_dump-failing-on-gitlab-instances-with-multiple-pg-read-replicas into master
What does this MR do and why?
Use the backup database connection while restoring timeouts. We can override the database settings for the backup and restore tasks to bypass the PgBouncer by setting environment variables that are prefixed with GITLAB_BACKUP_, but the ensure block tries to restore the timeouts using a regular connection without the overridden database settings.
