can be generated in a buffer and then sent to the frontend in a single
libpq call.  This solves problems with NOTICE and ERROR messages generated

more cleanups...of note, appendStringInfo now performs like sprintf(),
where you state a format and arguments.  the old behavior required
each appendStringInfo to have to have a sprintf() before it if any
formatting was required.

Also shortened several instances where there were multiple appendStringInfo()
calls in a row, doing nothing more then adding one more word to the String,
instead of doing them all in one call.

Many more cleanups...

	...malloc/free -> palloc/pfree
	...fopen/fclose -> AllocateFile/FreeFile
