Fix instability in parallel regression tests.
Commit f0c7b789a added a test case in case.sql that creates and then drops
both an '=' operator and the type it's for. Given the right timing, that
can cause a "cache lookup failed for type" failure in concurrent sessions,
which see the '=' operator as a potential match for '=' in a query, but
then the type is gone by the time they inquire into its properties.
It might be nice to make that behavior more robust someday, but as a
back-patchable solution, adjust the new test case so that the operator
is never visible to other sessions. Like the previous commit, back-patch
to all supported branches.
