How to connect to or open database without knowing the type of the relational database?

[kattungakrish]

I'm trying to implement a workflow using bun ORM in GO Lang, where given a data source name (dsn), I connect to and open the respective database without any knowledge of whether its SQLite, MySQL, PostgresSQL or MSSQL.

Currently, documented workflow in "Bun : for SQL Client in Go Lang", seems to require knowledge of the type of the database the client is trying connect to.

What I'm trying to achieve is a function:

func OpenBunDB( dataSourceName string) (*bun.DB , error)

Here dataSourceName can be a string containing a path to the SQLite db file or a dsn string for MySQL, PostgreSQL etc.
