I have currently an installed pgsql instance that is running on port 1486. I want to change this port to 5433, how should I proceed for this?

There should be a line in your postgresql.conf file that says:
port = 1486
Change that.
The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/
On Windows it is C:\Program Files\PostgreSQL\9.3\data
Don't forget to sudo service postgresql restart for changes to take effect.
You can also change the port when starting up:
$ pg_ctl -o "-F -p 5433" start
Or
$ postgres -p 5433
More about this in the manual.
