It's not an arbitrary limit -- users can easily change pg_config.h.

What if someone actually uses functions with more than 32
arguments? Their code will not longer be portable among
PostgreSQL installations, and they'll need to get the local
admin to recompile.

I could see adding a configure option if there was a justifiable
reason for using functions with more than 32 arguments -- but
IMHO that is quite a bizarre situation anyway, as Peter said.

My vote is to set the default # of function args to some
reasonable default (32 sounds good), and leave it at that.

Cheers,

Neil
