They might be contrasted with the comments for myLargeObjectExists.
Since we use MVCC visibility in loread(), metadata for large object
also should be visible in MVCC rule.
If I understand them, they say:
* pg_largeobject_aclmask_snapshot requires a snapshot which will be
used in loread().
* Don't use LargeObjectExists if you need MVCC visibility.

Ah, ACL_NO_RIGHTS is the default.

Hmmm, now it dumps not only comments but also ownership of large objects.
Should we rename it dumpBlobMetadata() or so?
