.SH "DESCRIPTION"
.PP

\fBALTER OPERATOR CLASS\fR
changes the definition of an operator class\&.
.PP
You must own the operator class to use
\fBALTER OPERATOR CLASS\fR\&. 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\(aqs schema\&. (These restrictions enforce that altering the owner doesn\(aqt do anything you couldn\(aqt do by dropping and recreating the operator class\&. However, a superuser can alter ownership of any operator class anyway\&.)
