I'm not sure exactly what has changed, nor at the moment how to fix it,
but I'm finding that pgxs no longer works for PL/R or dblink. Error as
follows:
make: *** No rule to make target
`/usr/local/pgsql-dev/lib/pgxs/src/makefiles/../../src/port/pg_config_paths.h',
needed by `all-static-lib'. Stop.
The problem is related specifically to Makefiles using MODULE_big. I
tested a few contribs that use MODULES and they seem to work fine under
pgxs.
