Looking at the relevant thread from 2020, this was still at the point
where we did not consider supporting 3.0 for all the stable branches
because 3.0 was in alpha:
https://www.postgresql.org/message-id/3d4afcfc-0930-1389-b9f7-59bdf11fb125@2ndquadrant.com
However, recent fixes like cab553a have made that possible, and we do
build with OpenSSL 3.0 across the whole set of stable branches.
Regarding the versions of OpenSSL supported:
- REL_13_STABLE requires 1.0.1 since 7b283d0e1.
- REL_12_STABLE and REL_11_STABLE require 0.9.8.
For 0.9.8, OPENSSL_API_COMPAT needs to be set at 0x00908000L (see
upstream's CHANGES.md). So I don't see a reason not to do as
suggested by Andres?
I have tested the attached patches across 11~13 with various versions
of OpenSSL (OPENSSL_API_COMPAT exists since 1.1.0), and this is
working here. Note that I don't have a MSVC environment at hand to
test this change on Windows, still `perl -cw Solution.pm` is OK with
it.
What do you think about the attached patch set (one for each branch)?
