File containing the Key for the X.509 certificate.
Syntax:
property SSLKey: String;
Description:
This parameter specifies the location for the secret key used for the client certificate. It can either specify a filename that will be used instead of the default %APPDATA%\postgresql\postgresql.key, or can specify an external engine (engines are OpenSSL loadable modules). The external engine specification should consist of a colon-separated engine name and an engine-specific key identifier.
