Overview

Comparisons against a PostgreSQL array column, named after the Ruby methods that mean the same thing: member? is Enumerable's element test, superset? and subset? are Set's whole-array containment, and intersect? is Array's "any element in common". Each name maps to one operator; the elements are rendered as an array literal, which PostgreSQL coerces to the column's element type, so any expression works as the operand and no schema lookup is needed.
