Well, it's not exactly a first-class citizen; compare for instance the
amount of verbiage in the docs about text I/O formats versus the amount
about binary formats.  But my question isn't about that; it's about why
aclitem should be considered a first-class citizen.  It makes me
uncomfortable that client apps are looking at it at all, because any
that do are bound to get broken in the future, even assuming that they
get the right answers today.  I wonder how many such clients are up to
speed for per-column privileges and non-constant default privileges for
instance.  And sepgsql is going to cut them off at the knees.
