* pgsql: Suppress new "may be used uninitialized" warning. @ 2026-02-17 02:05 Noah Misch <[email protected]> 0 siblings, 0 replies; 6+ messages in thread From: Noah Misch @ 2026-02-17 02:05 UTC (permalink / raw) To: [email protected] Suppress new "may be used uninitialized" warning. Various buildfarm members, having compilers like gcc 8.5 and 6.3, fail to deduce that text_substring() variable "E" is initialized if slice_size!=-1. This suppression approach quiets gcc 8.5; I did not reproduce the warning elsewhere. Back-patch to v14, like commit 9f4fd119b2cbb9a41ec0c19a8d6ec9b59b92c125.
