+Using /tmp for sockets allows everyone to spoof a PostgreSQL server. Thus use
+/var/run/postgresql/ for "system" clusters which run as 'postgres' (user
+clusters will still use /tmp). Since system cluster are by far the common case,
+set it as default.

+Subject: [PATCH] jit: Workaround potential datalayout mismatch on s390x
+
+LLVM's s390x target uses a different datalayout for z13 and newer processors.
+If llvmjit_types.bc is compiled to target a processor older than z13, and
+then the JIT runs on a z13 or newer processor, then there will be a mismatch
+in datalayouts between llvmjit_types.bc and the JIT engine.  This mismatch
+causes the JIT to fail at runtime.
