+Do not expose pg_trace.h (ie, <sys/sdt.h>) as something that every dependent
+package will need to #include successfully.  Otherwise we'd need to make
+postgresql-devel Require: systemtap-sdt-devel, which doesn't seem like a
+desirable thing to do.  This patch is already applied upstream and won't
+be needed in 8.3.7.
