Ah, sorry it really does not work.

However, I get following error on Solaris:

bash-3.2$ /usr/postgres/8.2/bin/postgres -D /tmp/db --share_buffers=16000
/usr/postgres/8.2/bin/postgres: illegal option -- share_buffers=16000
Try "postgres --help" for more information.

but following command works fine:

/usr/postgres/8.2/bin/postgres -D /tmp/db -c shared_buffers=16000

By my opinion problem is in getopt which interprets -- as a end of
options list.

Guideline 10

It maybe work on linux but I think it is not portable solution.
