Encrypted database source connector in AEP

Hello Team,

We are working with Postgres source connector and evaluating our options around Encryption. Based on our current understanding we have below possible options while building the connection string:

1) Connection without Encryption:
EncryptionMethod=0; ValidateServerCertificate=0.

2) Connection with Encryption but won't be validated at AEP end.
EncryptionMethod=1; ValidateServerCertificate=0.

3) Connection with Encryption and validation of certificate sent by PostgreSQL database.
EncryptionMethod=1; ValidateServerCertificate=1.

We would like to understand what are the configuration changes required at AEP end in case client want to connect over SSL encrypted connection (i.e option 2 or 3) ?
