Removes an operator family.
DROP OPERATOR FAMILY [IF EXISTS] <name> USING <index_method> [CASCADE | RESTRICT]
DROP OPERATOR FAMILY drops an existing operator family. To run 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.
Remove the B-tree operator family
DROP OPERATOR FAMILY float_ops USING btree;
This command will not succeed if there are any existing indexes that use the operator family. Add
CASCADE to drop such indexes along with the operator family.
There is no
DROP OPERATOR FAMILY statement in the SQL standard.
