PostgreSQL

Prepare

You will need the following information to create the connection:
  • Database host
  • Database port (default: 5432)
  • Database name
  • Username & password
By default, Noteable attempts to connect to PostgreSQL over SSL (default: Prefer). The options available are:
  • Prefer: first try an SSL connection; if that fails, try a non-SSL connection.
  • Require: only try an SSL connection.
  • Allow: first try a non-SSL connection; if that fails, try an SSL connection.
  • Verify-ca: only try an SSL connection and the server is verified by checking the certificate chain up to the root certificate stored on the client.
  • Verify-full: only try an SSL connection and the server is verified by checking the certificate chain up to the root certificate stored on the client and libpq will verify that the server hostname matches its certificate.
  • Disable: use a non-SSL connection.
If your data source is behind a firewall, you will need to ensure your firewall accepts incoming connections from Noteable. Read more: Data Connections​
