"make all" and "make install" at the top level don't touch the contrib subtree. If you already wiped your build tree, you'll have to recreate it --- be careful to give the same configure arguments as you used before. regards, tom lane ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.
