From 8268e66ac64cb846517580e0808f971343391fdf Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Wed, 10 Dec 2025 13:56:33 +0900 Subject: [PATCH] libpq: Authorize pthread_exit() in libpq_check pthread_exit() is added to the list of symbols allowed when building libpq. This has been reported as possible when libpq is statically linked to libcrypto, where pthread_exit() could be called.
