Feat: ⚡️ Add PostgreSQL support to storeContainer

[jffrancob]

What problem does your feature request solve?

Include PostgreSQL database support in addition to SQLite

Describe the solution you are proposing.

Looking at the example mdtest included in the whatsmeow library, there are two args (db-dialect and db-address) that can be used to determine the DB type and connection address. The main idea is to replicate these args in this project.

Describe alternatives you have considered.
