Can we start by defining in plain English what should define 2 PgArray instances as equal?
Should it mean they represent the same logical contents?
Should it mean the contain the exact same literal data?

If a select statement which returns an array is executed 10 times in a row, should all of the PgArray instances be considered equal?
