postgresql: one of the few ways to start postgresql db under different port.

nohup /usr/pgsql-9.3/bin/postgres -p 5433 -D /var/lib/pgsql/9.3/data &

OR

--Needs double code between the port. Otherwise, it will complain. Kept forgetting this after several weeks. The silly thing is, it should have complained about the -p instead of the port number.

-bash-4.1$ /usr/pgsql-9.3/bin/pg_ctl "-p 5433" -D /var/lib/pgsql/9.3/data start

sh:  5433: command not found

server starting

/usr/pgsql-9.3/bin/pg_ctl -o "-p 5433" -D /var/lib/pgsql/9.3/data start

-bash-4.1$ ps -ef|egrep '5432|5433'|grep -v grep
