There are two TAP tests in REL_17_STABLE that use the module
injection_points, and we have 6 of them on HEAD.  For now, I have
applied a patch that addresses the problems for v17 to avoid any
problems with the upcoming release, fixing the two tests that exist in
REL_17_STABLE.

For HEAD, I'd like to be slightly more ambitious and propose a routine
in Cluster.pm that scans for available extensions, as of the attached.
This simplifies the injection point test in libpq, as the
injection_point is one portion of the test so we don't need the check
based on the environment variable.  There is no need for checks in the
TAP tests injection_points's 001_stats.pl and test_slru's
001_multixact.pl as these modules disable installcheck.

Any thoughts about the attached?  This makes installcheck work here
with and without the configure switch.
