I'm not an SSL expert, so insert appropriate grain of salt, but AIUI the
question is what are you going to verify against?  You need some local
notion of which are your trusted root certificates before you can verify
anything.  So to default to verification would be to default to failing to
connect at all until user has created a ~/.postgresql/root.crt file with
valid, relevant entries.  That seems like a nonstarter.

It's possible that we could adopt some policy like "if the root.crt file
exists then default to verify" ... but that seems messy and unreliable,
so I'm not sure it would really add any security.
