What's the point in doing USE_PGXS builds with a full and configured
source present? The only thing I can think of is testing that pgxs
builds are working. In that case it doesn't seem helpful to fake
something into working which is then going to fail for real USE_PGXS
builds (where the original sourcetree won't be at that location
anymore).
Maybe I am missing something?
What we could do is something like:
ifdef USE_PGXS
$(warning "pg_xlogdump cannot be built using pgxs)
else
rest of the build rules
endif
i.e. only warn and do nothing if pgxs is specified so you can still do
make USE_PGXS in the contrib directory.
