A tour of the operator class facility

A PostgreSQL operator class tells the database server how to sort, match, and index values of a particular data type, and an operator family ties related data types together for the purpose of these operations. They constitute agreements between data type authors and data type-independent code, with most data types defining at least one operator class.
