Hi,

this is caused by a change between PG11 beta1 and beta2 which causes
several extensions to fail with that error message. Fixed by
recompiling the postgresql-11-powa packages.

Additionally, the testsuite was faulty in two ways, firstly it didn't
depend on postgresql-server-dev-all so pg_buildext was not available
which made the for-loop [1] a no-op, and secondly it didn't actually
invoke any functions, so it wouldn't have spotted this problem anyway.
(Now fixed in lines 11-14.)

Thanks for spotting and reporting!
