Hello Hackers.
I reworked the patch. Now, the syntax is similar to CREATE OPERATOR.
And as I wrote earlier problems with the cache I have not found. If someone
can suggest how it could be verified that would be happy.
New syntax example:
ALTER OPERATOR === (boolean, boolean) SET (COMMUTATOR = =);
ALTER OPERATOR === (boolean, boolean) SET (NEGATOR = =);
ALTER OPERATOR === (boolean, boolean) SET (RESTRICT = example_func);
ALTER OPERATOR === (boolean, boolean) SET (JOIN = example_func);
ALTER OPERATOR === (boolean, boolean) SET (
COMMUTATOR = NULL,
NEGATOR = NULL,
RESTRICT = NULL,
JOIN = NULL
);
Thanks!
