Description:

Your documentation states that the minimum requirement is OpenSSL 1.0.x
version: "OpenSSL is also required for random number generation on platforms
that do not have /dev/urandom (except Windows). The minimum required version
is 1.0.1". But when I tried to use the pg_dump utility, I got an error:
"error while loading shared libraries: libcrypto.so.1.1: cannot open shared
object file: No such file or directory"
And libcrypto.so.1.1 refers to the OpenSSL 1.1.x version.
The current version 17 also says 1.0.. I suspect that 1.1x is needed there
too.
