Under what circumstances would such a plug-in use OpenSSL directly? Could
you explain in more detail what you are trying to do?
I did not know that - I use it to check the library version at compile
time with PG_VERSION_NUM / PG_MAJORVERSION_NUM to see which features
are available. This is about a client using libpq, not a server-side
plugin.
Obviously, PQlibVersion() is a function that can only be used at
runtime, and it's too late then.
Other than those macros in pg_config.h, I could not find any other
compile-time way to check the libpq version.
What specifically are you trying to check for in libpq? Maybe there is
a better way, or we could add one.
