Hi,
I add a tiny test to pg_checksum for coverage.
I checked it improve test coverage 77.9% -> 87.7%.

+# Checksums are verified if --progress arguments are specified
+command_ok(
+    [ 'pg_checksums', '--progress', '-D', $pgdata ],
+    "verifies checksums as default action with --progress option");
+
+# Checksums are verified if --verbose arguments are specified
+command_ok(
+    [ 'pg_checksums', '--verbose', '-D', $pgdata ],
+    "verifies checksums as default action with --verbose option");

This isn't really true, --progress or --verbose doesn't enable checksum
verification, it just happens to be the default and thus is invoked when called
without a mode parameter.

As written these tests aren't providing more coverage, they run more code but
they don't ensure that the produced output is correct.  If you write these
tests with validation on the output they will be a lot more interesting.
