Hello, This is new version of patch for dblink using row processor.

 - Use palloc to allocate temporaly memoriy blocks.

 - Memory allocation is now done in once. Preallocate a block of
   initial size and palloc simplified reallocation code.

 - Resurrected the route for command invoking. And small
   adjustment of behavior on error.

 - Modification to fix connection name missing bug is removed out
   to another patch.

 - Commenting on the functions skipped over by lonjmp is
   withholded according to Marko's discussion.

 - rebased to e8476f46fc847060250c92ec9b310559293087fc
