Hello,
the documentation for ALTER EXTENSION is missing the description for
the arguments of the form ADD OPERATOR name (left_type, right_type).
Albeit it's pretty obvious what they are, it is not so obvious what to
do for unary operators (i.e. replace the type on the missing side with
NONE).
Patch to fix the doc attached.
