I think PG_VERSION_NUM should be handled by the standard
PG_MODULE_MAGIC. But an integer for the validator version would be
good, I think.

That was from Peter's request up in [1]. (I don't have strong opinions
on which to support, but I am vaguely persuaded by the idea of parity
between Meson and Autoconf.)

Doesn't the PKG_CONFIG_PATH envvar let you do that for Autoconf? Or,
if you're using Meson, -Dpkg_config_path? I was using the latter for
my local Curl builds.

Hmm, I wonder if Meson supports alternative names for pkg-config.
Though I guess the --version handling would be different between the
two?
