DROP OPERATOR FAMILY — remove an operator family
DROP OPERATOR FAMILY [ IF EXISTS ]name
USINGindex_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.
IF EXISTS
Do not throw an error if the operator family does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of an existing operator family.
index_method
The name of the index access method the operator family is for.
CASCADE
Automatically drop objects that depend on the operator family, and in turn all objects that depend on those objects (see Section 5.14).
RESTRICT
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.
