PGP does not implement "partial length headers" which are needed for 
encrypting a stream (of unknown size).  The workaround in PGP is to
use a temporary file.

GnuPG uses partial length headers to do the encryption and due to
--rfc1991 it should use a pre-OpenPGP way to encode partial lengths.

There is no way to do it.  Maybe pgpgpg has the workaround too.
