Databases for PostgreSQL connection
To access your data in Databases for PostgreSQL, create a connection asset for it.
Databases for PostgreSQL is an open source object-relational database that is highly customizable. It’s a feature-rich enterprise database with JSON support.
Create a connection to Databases for PostgreSQL
To create the connection asset, you need these connection details:
- Database name
- Hostname or IP address of the database
- Port number
- Username and password
- SSL certificate (if required by the database server)
For Credentials and Certificates, you can use secrets if a vault is configured for the platform and the service supports vaults. For information, see Using secrets from vaults in connections.
