postgres connection with port option in shell script

Hi,

      I want to get postgres connection in script file. I am executing below command and successfully getting connected --- 

psql postgresql://$USER:$PASSWORD@$HOST/$DATABASE <<END

select * from abc;

This is executing with default 5432 port.If postgres is installed to any other port then port option need to be include here[Don't want to take port from .pgpass file].

How I can modify this command with PORT option.

Thanks
