Remove setvbuf() call from PQtrace()
It's misplaced there -- it's not libpq's output stream to tweak in that
way. In particular, POSIX says that it has to be called before any
other operation on the file, so if a stream previously used by the
calling application, bad things may happen.
Put setvbuf() in libpq_pipeline for good measure.
Also, reduce fopen(..., "w+") to just fopen(..., "w") in
libpq_pipeline.c. It's not clear that this fixes anything, but we don't
use w+ anywhere.
Per complaints from Tom Lane.
