We're talking about <-> semantic changing based on PostgreSQL version,
right ? That's not the only case of PostgreSQL version dependent behavior,
another one is presence or absence of the whole index-assisted KNN.

The only idea I have about this is to expose the version of PostgreSQL
PostGIS was built against so that postgis_full_version() can complain
about it and recommend a re-build/re-install. Then we need to also
allow for upgrades between same versions as we already do with the
"next" trick.
