Probably.  But I would write just "type numeric".  We do not generally
acknowledge "decimal" as a separate type, because for us it's only an
alias for numeric (there is not a pg_type entry for it).

Also, that leads to the thought that "numeric argument ... is out of
range for type numeric" seems either redundant or contradictory
depending on how you look at it.  So I suggest wording like

argument "...input string here..." of jsonpath item method .%s() is out of range for type numeric

Agreed, so I suggest the above.
