Postgres Sink v0.3.0

Bring support for TLS connections.

Changed

• Breaking: use TLS by default. You can revert to the old insecure
  connection by using the --no-tls=true CLI flag, or setting
  sinkOptions.noTls: true in your script.

Added

• You can now connect to PostgreSQL securely using TLS connections. The TLS
  connection can be customized by providing a self-signed certificate, or by
  enabling/disabling certificate and hostname validation.
