-    Fix copy/paste error in FindPostgres.cmake
-    
-    In f51c6b1513e312002c108fe87d26e33c48671406, EXEC_PROGRAM was changed to
-    execute_process. As part of that, it looks like the second and third
-    invocations were accidentally changed.

-    On Apple, use FIND_LIBRARY to locate libpq
-    
-    I think FIND_LIBRARY() is better than just relying on what pg_config
-    said its libdir was, since, depending on how libpq was installed, it may
-    or may not be in that directory. If its not, FIND_LIBRARY() is able to
-    find it in other locations.
