I created an equality operator for aclitem, and then all was well until
I finished the above (i.e. I created array-array operators for "<>",
"<", ">", "<=", and ">=" based on the text comparison analogy). Now on
ANALYZE (and therefore on initdb) I get this:

template1=# analyze;
ERROR:  Unable to identify an ordering operator for type aclitem
         Use an explicit ordering operator or modify the query

This is where I ran into the problem with an equality operator earlier.
Problem this time is that an ordering operator makes no sense for
aclitems -- does it? Any thoughts on how to work around this?
