NAME

DROP OPERATOR CLASS - remove an operator class

 

SYNOPSIS

DESCRIPTION

DROP OPERATOR CLASS drops an existing operator class. To execute this command you must be the owner of the operator class.  

PARAMETERS

index_method
The name of the index access method the operator class is for.
CASCADE
Automatically drop objects that depend on the operator class.
RESTRICT
