Yes. I started going through the comments tonight. Partial patch
attached. There were two comments that I was unable to understand and
therefore could not reword - the one at the top of
pg_largeobject_aclmask_snapshot(), and the second part of the comment
at the top of LargeObjectExists():

* Note that LargeObjectExists always scans the system catalog
* with SnapshotNow, so it is unavailable to use to check
* existence in read-only accesses.

In both cases, I'm lost. Help?

In acldefault(), there is this comment:

/* Grant SELECT,UPDATE by default, for now */

This doesn't seem to match what the code is doing, so I think we
should remove it.

I also notice that dumpBlobComments() is now misnamed, but it seems
we've chosen to add a comment
mentioning that fact rather than fixing it. That doesn't seem like
the right approach.
