Hmm,
It depends what APIs in Postgres are being used in PostGIS. We have
modified a quite a few internal functions and structures e.g.
standard_ProcessUtility() to work in cluster environment. Using those
functions would break the object linkages. But anything which is SQL
compatible with 10.1 will work against PGXC 2.0 if we get to catch up with
PG by then. One may not need to modify the code in such cases, but would
require to build the extension or binary again.
