Re: [pgsql-hackers-win32] snprintf causes regression

From what I recall from the conversation, I would say rename the vsprintf
and the sprintf functions in postgres to pq_vsnprintf and pq_snprintf.
Define a couple macros: (in some common header, pqprintf.h?)

#define snprintf pq_snprintf
#define vsnprintf pq_snprintf

Then just maintain the postgres forms of printf which have seemed to be OK
except that on Win32 vnsprintf, although in the same object file was not
being used.
