(Operators and functions that + are essential to indexes should be grouped within the relevant operator + class, rather than being <span class="quote">“<span class="quote">loose</span>”</span> in the operator family. + Typically, single-data-type operators are bound to operator classes, + while cross-data-type operators can be loose in an operator family + containing operator classes for both data types.) + </p><p> + The new operator family is initially empty. It should be populated + by issuing subsequent <code class="command">CREATE OPERATOR CLASS</code> commands + to add contained operator classes, and optionally + <code class="command">ALTER OPERATOR FAMILY</code> commands to add <span class="quote">“<span class="quote">loose</span>”</span> + operators and their corresponding support functions. + </p><p> + If a schema name is given then the operator family is created in the + specified schema. Otherwise it is created in the current schema. + Two operator families in the same schema can have the same name only if they + are for different index methods. + </p><p> + The user who defines an operator family becomes its owner.
