I recommend posting this to pgsql-admin or pgsql-general instead of pgsql-docs
to get more responses. Besides that, pgsql-docs is for discussions on the
Postgres docs.

The OWASP Cheat Sheets give advice on securing web applications:

My general advice: design and implement for correctness, then measure and
optimize. For performance, look into high availability:

Use pgBackRest or pgbarman with WAL streaming to reduce the recovery point
objective (the maximum period in which data might be lost).

Some cloud providers offer Postgres instances including backups, e.g. Google
Cloud Platform which I'm looking into right now.
