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.

We must cast the arguments of <ctype.h> functions to unsigned
char to avoid problems where char is signed.
Speaking of which, considering that this *is* a <ctype.h> function,
it's rather remarkable that we aren't seeing more complaints about
not having included that header.
Per buildfarm.
Remove confusion between time_t and pg_time_t; neither
gettimeofday() nor localtime() deal in the latter.
libpq indeed has no business using <pgtime.h> at all.
Use snprintf not sprintf, to ensure we can't overrun the
supplied buffer. (Unlikely, but let's be safe.)
Per buildfarm.
Transform the PQtrace output format from its ancient (and mostly
useless) byte-level output format to a logical-message-level output,
making it much more usable. This implementation allows the printing
code to be written (as it indeed was) by looking at the protocol
documentation, which gives more confidence that the three (docs, trace
code and actual code) actually match.
