From 1ddb9e14eadf95802c835a3754af5621615ded30 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 9 May 2025 11:50:33 -0400 Subject: [PATCH] Centralize ssl tests' check for whether we're using LibreSSL. Right now there's only one caller, so that this is merely an exercise in shoving code from one module to another, but there will shortly be another one. It seems better to avoid having two copies of this highly-subject-to-change test. Back-patch to v15, where we first introduced some tests that don't work with LibreSSL.
