DROP OPERATOR FAMILY(7) PostgreSQL 9.5.0 Documentation
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
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.
