Subject: pgsql: Add overflow checks to money type.
Date: Fri, 19 Jul 2024 16:55:33 +0000
Message-ID: <E1sUqtJ-000I0q-UC@gemulon.postgresql.org> (raw)
Add overflow checks to money type.
None of the arithmetic functions for the the money type handle
overflow. This commit introduces several helper functions with
overflow checking and makes use of them in the money type's
arithmetic functions.
Fixes bug #18240.
