Whenever I try to restore a dump database backup to PostgreSQL version 17.1, I receive the following error log. The dump is from PostgreSQL version 15.8.

What is this error and how can I fix it?.

pg_restore: error: could not execute query: ERROR: commutator operator - is already the commutator of operator +

Command was: CREATE OPERATOR adempiere.- (

FUNCTION = adempiere.subtractdays,

LEFTARG = interval,

RIGHTARG = numeric,

COMMUTATOR = OPERATOR(adempiere.-)

);

pg_restore: error: could not execute query: ERROR: operator does not exist: interval adempiere.- numeric

Command was: ALTER OPERATOR adempiere.- (interval, numeric) OWNER TO adempiere;

With Best Regards
