The problem was with getopt which is works little bit differently when -
is specified in optstring. If you look in POSIX it does not define how
getopt should work in this case. Solaris getopt implementation has
extension for long args. Unfortunately PostgreSQL clashes with it,
because it does not use getopt_long for long argument, but getopt(argc,
argv,"xy-").

yes and it will exist forever, because it is public API.
see man -s3C getopt

I understand, I'm not happy too :(, but how Tom mentioned it has been
never supposed to work. See documentation

getopt_long is OK. Problem is getopt. getopt in core is currently taken
from *BSD but it could be updated.
One possible solution should be to use internal getopt only for postgres
binary and for other to use solaris libc version.
