Warn about mixed use of connectionString and ssl

[chornsby]

I tripped over this case today when handling client code which used both connectionString and ssl configuration options and the former unexpectedly overrides the latter.

The relevant code that handles this is here:
https://github.com/brianc/node-postgres/blob/4b229275cfe41ca17b7d69bd39f91ada0068a5d0/packages/pg-connection-string/index.js#L68-L70

Thanks! Sorry you ran into that issue, hopefully I can fix that soon. 😄

Hi,
When I specify sslmode in the ssl configuration options, it is not honoured.
When I specify sslmode in connection string instead, it fails with "Error: self signed certificate in certificate chain"

Please suggest a way to be able to provide sslmode

[ksrtilak]

If I use rejectUnauthorized as true, along with ca, key and cert
Is this equivalent to sslmode as verify-full ?

@ksrtilak Yes.

Thanks for your confirmation.

Please help with these as well:

• For sslmode = required. only key and cert are mandatory, Is this correct ?
• Which sslmode needs both password and key/cert pair ?

@ksrtilak Yes.
