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.
