So they'd be compatible, while openssl's license is nominally incompatible with GPL. As I recall, Debian jumps through some silly hoops to pretend that they're not using openssl and readline at the same time with Postgres, so I can definitely understand Christoph's interest in an alternative. However, judging from the caveats mentioned in the initial message, my inclination would be to wait awhile for wolfSSL to mature. In any case, the patch as written seems to *remove* the option to compile PG with OpenSSL. The chance of it being accepted that way is indistinguishable from zero. We've made some efforts towards separating out the openssl-specific bits, so the shape I'd expect from a patch like this is to add some parallel wolfssl-specific bits. There probably are more such bits to separate, but this isn't the way to proceed. regards, tom lane
