Where did you get the libpq source from?

What was the command you used to compile?

Do you have openssl-dev(el) installed?

The answer to the second question is that libpq is compatible with
OpenSSL 1.1.0 since this commit:
commit: 593d4e47db7af1a3a5dd6b6b1971f181b5566dbd
author: Heikki Linnakangas <heikki.linnakangas@iki.fi>

Support OpenSSL 1.1.0.

This applies down to 9.5.  Porting got a bit more difficult with 9.4 and
older versions.  As 1.0.2 is LTS, meaning that it will become EOL after
1.1.0, porting 1.1.0 does not matter much as most application are going
to use 1.0.2 in priority (I do so for one).

Most likely that's the problem.  Debian does this package split for
example.

The answer to this question should be yes.  (Please note that no
Windows buildfarm machines use openssl 1.1.0 as far as I can see, I
myself build stuff with 1.0.2 on Windows.)

No changes should be needed as far as I know in the scripts in
src/tools/msvc.  The set of APIs present in 1.1.0 is the same whatever
the platform so the compatibility is the same, and the dependent
libraries should be ssleay32.lib and libeay32.lib whose location depend
on your installation of OpenSSL.
