From 9c2e660b07fc16bdd79c25047cce6cde2acb3f37 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Tue, 2 Jul 2024 09:24:04 +0200 Subject: Limit max parameter number with MaxAllocSize MaxAllocSize puts an upper bound on the largest possible parameter number ($268435455). Use that limit instead of INT_MAX to report that no parameters exist beyond that point instead of reporting an error about the maximum allocation size being exceeded.
