[postgis-users] postgis_inout.c with pgres < 73

[Dave Blasby]

Quoting strk <strk@freek.keybit.net>:

> PG_NARGS is not defined in fmgr.h < 7.3
> It is used with no check in postgis_inout.c  (multiple times)
> 
> All checks can be substituted with the macro
> PG_ARGISNULL() available also on the older pgres versions.

Thanks strk - I'll apply that patch on monday.  I thought I had seen PG_NARGS() 
in 7.1 - my bad.

Yuri's also commited a memory-leak fixed GEOS, so (on monday) I'll also patch 
up the GEOS bridge...
