Meh. This is pretty far from a complete patch: it introduces an
undocumented configure switch, and it changes the default value for a GUC
without fixing either the corresponding SGML documentation or the
postgresql.conf.sample line for it.
While it would surely be possible to build all the infrastructure to make
that work right, I'm not really sure that we want to carry around that
much baggage for a single-system hack.
A compromise that might be worth considering is to introduce
#define PG_DEFAULT_SSL_CIPHERS "HIGH:MEDIUM:+3DES:!aNULL"
into pg_config_manual.h, which would at least give you a reasonably
stable target point for a long-lived patch.
