The settings are specific to each supported platform. If you want to list all available databases, go to tab Server and click Load databases. Note: For PostgreSQL connections you can also easily select a schema or multiple schemas (see screenshot above).
Secure SSH or SSL/TLS database connections
The settings allow you to create a secure connection to your databases. SSH, SSL/TLS settings are available in the Professional edition.
