Thread: psql and jdbc default sslmode

We are making connections to the postgres server through jdbc and psql (libpq) . I have set the ssl as on the postgres server . It can take ssl as well as non ssl connections. 

I made a connection through a psql client to postgres server and could confirm that the default sslmode (when no sslmode parameter is supplied while making connection) is "prefer". Please note i have not supplied the sslmode parameter in the connection string from psql. Still connection is secured 

 psql "postgresql://$POSTGRES_HOST:$PG_PORT/postgres" -U postgres
psql (9.6.18, server 9.6.12)
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384, bits: 256, compression: off)
Type "help" for help.

I have read in the AWS documentation for jdbc connections to server  the default mode is "verify-full". I created a jdbc connection to the postgres server by supplying no sslmode to the connection string . The connection was successful . I just want to confirm what is the default sslmode for jdbc connections to the postgres server when ssl is turned on the server.
