TBH, I think this entire discussion has gone seriously off into the
weeds. The original design where we just let a shared_preload_library
function get into a hook is far superior to any of the overcomplicated
kluges that are being discussed now. Something like this, for instance:
>>> ssl_passphrase_command='#superlib.so,my_rot13_passphrase'
makes me positively ill. It introduces problems that we don't need,
like how to parse out the sub-parts of the string, and the
quoting/escaping issues that will come along with that; while from
the user's perspective it replaces a simple and intellectually-coherent
variable definition with an unintelligible mess.
