Ability to protect databases

[Gurjeet Singh]

Feature request

Please add the ability to protect the databases, as well.

Describe the solution you'd like

It should be possible to protect some databases, e.g. supabase_operator_db, so that a customer cannot accidentally drop or modify the databases that are critical to the proper functioning of the Postgres Instance.

Describe alternatives you've considered

None.

Additional context

Since all SQL operations require a database connection, usually the PGaaS provider must connect to some well-defined set (containing at least one DB) of databases. If those databases are dropped, or modified in some way, the health of the DB instance and that of the PGaaS may be at risk.

It may be necessary to even prevent a customer from connecting to these potentially sensitive databases.
