Postgres uses their own protocol with STARTTLS-like interface to
initiate SSL handshake, see here:
https://www.postgresql.org/docs/current/protocol-flow.html#id-1.10.6.7.12
That is, it's not going to work with neither SSL termination, nor
SSL preread, and needs an implementation of the Postgres protocol.
