Looking at the sendmail code, it seems they use SPT_REUSEARGV (what we
call PS_USE_CLOBBER_ARGV) technique on Solaris.  Possibly the problem is
simply that line 65 in src/backend/utils/misc/ps_status.c fails to
cover Solaris as one of the possible options:

#elif defined(__linux__) || defined(_AIX4) || defined(_AIX3) || defined(__sgi) || (defined(sun) && !defined(BSD)) || defined(ultrix) || defined(__ksr__) || defined(__osf__) || defined(__QNX__) || defined(__svr4__) || defined(__svr5__)
#define PS_USE_CLOBBER_ARGV

Can someone check whether adding an appropriate Solaris symbol (which
one?) fixes the problem?

The coding technique embodied in lines 63-67 pretty much sucks anyway,
since this platform-specific knowledge ought to be out in the port.h
files rather than hidden in the guts of the system.  I don't want to
touch it right now, but I think we ought to have things like

	#define PS_STATUS_TECHNIQUE PS_USE_CLOBBER_ARGV

in the port.h files, rather than these massive #ifdefs.
