Yawn. We've had this in Perl for decades using the DBI Shell (dibsh). DBI is a common database interface. To connect to a data source, one uses an appropriate driver (by convention, in the DBD name space, such as DBD::Pg or DBD::MySQL) to get a db handle that can run SQL commands. There are a lot of drivers for things like CSV files, in memory database, etc.

Plus you can access all this programmatically and not just through the dbish command. Since this is a central part of Perl infrastructure, there are a ton of tools that extend the DBI, from a variety of ORMs like DBIx::Class, to data export and even DDL delta management.
