I didn't mean to reopen the whole SSL compression can of worms here, I
was mistaken about the level of support left after PG14. I was merely
lightly annoyed that the psql startup display got quite long with not
very interesting information.

I propose a reduced patch that just removes the "bits" display, since
that is redundant with the "cipher" display.
