Description:
When running 'TESTS="$(printf "tablespace %.0s" `seq 1000`)" make
check-tests' I get:
============== running regression test queries ==============

test tablespace ... FAILED

and so on...

============== shutting down postmaster ==============
===========================
403 of 1000 tests failed.

The differences that caused some tests to fail can be viewed in the
file ".../src/test/regress/regression.diffs". A copy of the test summary
that you see
above is saved in the file ".../src/test/regress/regression.out".

It seems that the following query in src/test/regress/sql/tablespace.sql:
SELECT relname, spcname FROM pg_catalog.pg_tablespace t, pg_catalog.pg_class
c
where c.reltablespace = t.oid AND c.relname LIKE 'part%_idx';
needs an "ORDER BY".
