Commitaa606b931installed a test that would reference a nonexistent TupleDesc array entry if a system column is used in COPY FROM WHERE. Typically this would be harmless, but with bad luck it could result in a phony "generated columns are not supported in COPY FROM WHERE conditions" error, and at least in principle it could cause SIGSEGV. (Compare570e2fcc0which fixed the identical problem in another place.) Also, sincec98ad086ait throws an Assert instead. In the back branches, just guard the test to make it a safe no-op for system columns. Commit21c69dc73installed a more aggressive answer in master.
