Fix for segmentation fault in PCP processor: Bug 598

The crash was caused by an unconditionally pfree on buf without verifyingif it
was actually allocated or not. And freeing the but was not actually required at
the first places since the associated MemoryContext always gets resets anyway
after each loop iteration.
