I'm not saying there's no attack possible here (although I cannot
think of one), but we allow configuring every other SSL option using
an env var^1. So if there is an attack possible, why would that only
apply to being able to control the sslkeylogfile as opposed to e.g.
sslmode or sslrootcert.

^1 except for "sslpassword", which is weird because that seems exactly
like one of the options you might not want to store in a connection
string for security reasons.
