Support for PostgreSQL or MariaDB as a backend for the Grype database

Hello,

First of all, thank you for the work you are doing around open-source tools for vulnerability and SBOM management.

The Grype database you use is very powerful, but its usage is currently limited to a SQLite database. Do you think it would be possible for the database to be inserted into, or even directly created in, a database such as PostgreSQL or MariaDB?

This would be really interesting to simplify interactions with the database in certain contexts.

What do you think?
