* The user is required to specify a table name and database connection
information in the configuration file.
* INSERTs and DELETEs are done via prepared statements for speed.

* Creates the table if it does not exist with the given table name using
a query like:
CREATE TABLE myminio (
key varchar PRIMARY KEY,
value JSONB
);
* Vendors some required libraries.
