TLS certificate when connecting to postgressql db
I am running into a TLS certification error when trying to connect to a postgressql db hosted on ibm cloud 
```
A serious error occurred when building the initial schema. Exiting because `retryOnInitFail` is not set. Error details:

Error: self signed certificate in certificate chain
    at TLSSocket.onConnectSecure (_tls_wrap.js:1474:34)
    at TLSSocket.emit (events.js:310:20)
    at TLSSocket._finishInit (_tls_wrap.js:917:8)
    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:687:12)
```

Please advise.
