You must own the operator class to use ALTER OPERATOR CLASS. To alter the owner, you must also be a direct or indirect member of the new
owning role, and that role must have CREATE privilege on the operator class's schema. (These restrictions enforce that altering the owner
doesn't do anything you couldn't do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator

The name of the index method this operator class is for.
The new name of the operator class.

DROP_OPERATOR_FAMILY - remove an operator family
DROP OPERATOR FAMILY [ IF EXISTS ] name USING index_method [ CASCADE | RESTRICT ]
DROP OPERATOR FAMILY drops an existing operator family. To execute this command you must be the owner of the operator family.
DROP OPERATOR FAMILY includes dropping any operator classes contained in the family, but it does not drop any of the operators or functions
referenced by the family. If there are any indexes depending on operator classes within the family, you will need to specify CASCADE for
the drop to complete.
Do not throw an error if the operator family does not exist. A notice is issued in this case.
The name (optionally schema-qualified) of an existing operator family.
The name of the index access method the operator family is for.
Automatically drop objects that depend on the operator family.
Refuse to drop the operator family if any objects depend on it. This is the default.
Remove the B-tree operator family float_ops:
DROP OPERATOR FAMILY float_ops USING btree;
This command will not succeed if there are any existing indexes that use operator classes within the family. Add CASCADE to drop such
indexes along with the operator family.
There is no DROP OPERATOR FAMILY statement in the SQL standard.
