feat: sslnegotiation and direct ssl for postgres 17 #1151

Open sunng87 opened 1 week ago

sunng87 commented 1 week ago

This patch adds Direct SSL support which is a new feature coming in PostgreSQL 17. With this option, we issue TLS handshake directly without SslRequest. This will save a roundtrip on connection opening.

I just follow how libpq is designed, to offer an option sslnegotiation to control this behaviour (because it won't work on Postgres 16 or earlier).

Seems reasonable to me, but I think it might make sense to wait on merging until 17 releases.

No problem. I'm using this to test my own postgresql wire protocol implementation

And the clippy issue seems not related to this patch, I can create another one to fix that. Edit: Just saw it's been fixed on default branch
