Обсуждение: pgsql: Add pg_add_size_overflow() and friends
Add pg_add_size_overflow() and friends Commit 600086f47 added (several bespoke copies of) size_t addition with overflow checks to libpq. Move this to common/int.h, along with its subtraction and multiplication counterparts. pg_neg_size_overflow() is intentionally omitted; I'm not sure we should add SSIZE_MAX to win32_port.h for the sake of a function with no callers.
