Brooks Davis 8bff61a6ba Reduce NL_ARGMAX to 4096 to match Linux.
NL_ARGMAX is the maximum number of positional arguments supported by
printf(3). Prior to r308145 it was declared as 99 and not enforced.
r308145 added enforcement and increased the value to 64k.

Unfortunately, development versions of PostgreSQL used the system
definition to allocate and zero an NL_ARGMAX * 4 sized array on the
stack of its snprintf implementation with measurable performance
impacts. This has been fixed in new PostgreSQL versions, but it is
possible that other programs suffer from this problem.

A value of 4096 puts us on par with Linux and is certainly large enough
for any reasonable program.
