Re: Proposal for async support in libpq

 for one, it is not encrypted,
 for two, the receiving end doesn't listen for OOB (most likely because
sending side doesn't encrypt it)
  The sending side doesn't encrypt it because OOB concept (flushing unsent
data) is incompatible with simple *single-stream* encryption. flushing
breaks the decryption of the data -- it corrupts the stream, so it becomes
unencryptable.
