The test man page says absolutely nothing about how the [[ expr ]] compound command behaves in various shells. In some shells, [[ is an unknown command; in others it is a keyword in the syntax for that shell. There is a huge difference between the way a shell handles an unquoted $* when arguments are part of the shell's syntax versus when arguments are being parsed as arguments for a utility to be invoked (even if it is a built-in utility as in the case of test and [).

ALTER 
OPERATOR(7) SQL Commands ALTER OPERATOR(7) NAME
ALTER OPERATOR - change the definition of an operator SYNOPSIS
ALTER OPERATOR name ( { lefttype | NONE } , { righttype | NONE } ) OWNER TO newowner DESCRIPTION
ALTER OPERATOR changes the definition of an operator. The only currently available functionality is to change the owner of the operator. You must own the operator to use ALTER OPERATOR. 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's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the operator. However, a superuser can alter ownership of any operator anyway.) PARAMETERS
name The name (optionally schema-qualified) of an existing operator. lefttype The data type of the operator's left operand; write NONE if the operator has no left operand. righttype The data type of the operator's right operand; write NONE if the operator has no right operand. newowner The new owner of the operator. EXAMPLES
Change the owner of a custom operator a @@ b for type text: ALTER OPERATOR @@ (text, text) OWNER TO joe; COMPATIBILITY
There is no ALTER OPERATOR statement in the SQL standard. SEE ALSO
