Also, which platform are you running the Apiman Manager on. WildFly,
EAP, Tomcat, Jetty, etc?
Would be interested to see you try the newest Postgres driver. e.g.
https://jdbc.postgresql.org/download/postgresql-42.1.1.jar

Hi Andy,
Can you describe how your API, ClientApp & Plan is set up?
e.g.
API = [Keycloak OAuth2 Policy]
Plan = [<nothing>]
ClientApp = [Header Policy]
Regards,
Marc
