To conclude this thread -- it was reported that the patches I did to
break the initialization of libssl have solved the issue. Postgres
module connects ok when tls module is loaded. Also, tls connections
seems to work as expected. Patches are for now in master and 4.2
branches (backport to 4.1 also considered).
Cheers,
Daniel
