Bug reference:      6664
Logged by:          Karthik Ananth

PostgreSQL version: 9.0.7

As per the documentation by default postgres server should run in
foreground. I am referring to this link -
http://www.postgresql.org/docs/9.0/static/server-start.html

But what I have observed is, it is not happening and the command returns
immediately.  Below is the transcript -=20

c670e04:rkananth 16] /usr/local/bin/postgres --version=20
