English manual definition

Are aclitem s equal? (Notice that type aclitem lacks the usual set of comparison operators; it has only equality. In turn, aclitem arrays can only be compared for equality.)

'calvin=r*w/hobbes'::aclitem = 'calvin=r*w*/hobbes'::aclitem → f

Catalog interpretation

The catalog pg_operator stores information about operators. See CREATE OPERATOR and Section 36.14 for more information.
