RStudio Package Manager HA load balancing without PostgreSQL

Reading about HA & load balancing for RStudio Package Manager here
" 1. HA requires using a PostgreSQL database. All nodes in the cluster must use the same PostgreSQL database."

It seems for HA PostgreSQL DB is a must. Challenge is if an Open source technology is not already an approved standard for the organization it is extremely challenging and time-consuming to either get a waiver or to standardize it.

Hence, I am wondering if there is a way to implement HA for Package Manager with any other DBs i.e. SQL Server, Oracle DB, MongoDB, MySQL etc.
Thank you in advance for your response.

Thank you for your feedback. Today Package Manager only supports Postgres, but we'll note the request for future consideration.

One thing to keep in mind, this database is specific to the application, your team will not need to do any administration of the data records aside from the initial setup, so you won't need a DBA. Many organizations are able to get approval for the application database as part of the Package Manager review process (instead of starting a second, separate approval process).
