My compiler is unhappy about this one:
../postgresql/src/bin/pg_test_fsync/pg_test_fsync.c:605:2: error: ignoring
return value of ‘write’, declared with attribute warn_unused_result
[-Werror=unused-result]
605 | write(STDOUT_FILENO, "\n", 1);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I think we need to do something like the following, which is similar to
what was done in aa90e148ca7, 27314d32a88, and 6c72a28e5ce.
diff --git a/src/bin/pg_test_fsync/pg_test_fsync.c
