No, it does not, because lo_export writes the data to a file on the
server side --- the data does not pass across the encrypted connection.
It still appears that there's an issue with moving a large chunk of
data across the link.
Whether this is OpenSSL's fault or libpq's is not clear. I'm prepared
to believe that we are not using SSL_read correctly, but if so, what
is the correct way? The OpenSSL docs are not very clear on how one
does asynchronous reads.
