Add CREATE/ALTER/DROP OPERATOR FAMILY commands, also COMMENT ON OPERATOR 

FAMILY; and add FAMILY option to CREATE OPERATOR CLASS to allow adding a
class to a pre-existing family.  Per previous discussion.  Man, what a
tedious lot of cutting and pasting ...

<title>Description</title>
<para>
<command>CREATE OPERATOR FAMILY</command> creates a new operator family.
An operator family defines a collection of related operator classes,
and perhaps some additional operators and support functions that are
compatible with these operator classes but not essential for the
functioning of any individual index. (Operators and functions that
are essential to indexes should be grouped within the relevant operator
class, rather than being <quote>loose</> 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.)
</para>
<para>
The new operator family is initially empty. It should be populated
by issuing subsequent <command>CREATE OPERATOR CLASS</command> commands
to add contained operator classes, and optionally
<command>ALTER OPERATOR FAMILY</command> commands to add <quote>loose</>
operators and their corresponding support functions.
</para>
<para>
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.
</para>
<para>
The user who defines an operator family becomes its owner. Presently,
the creating user must be a superuser. (This restriction is made because
an erroneous operator family definition could confuse or even crash the
server.)
</para>
<para>
<command>CREATE OPERATOR FAMILY</command> does not presently check
whether the operator family definition includes all the operators and
functions required by the index method, nor whether the operators and
functions form a self-consistent set. It is the user's
responsibility to define a valid operator family.
