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



If all you are going to do is substitute environment variables into a URI why not just identify the environment variables that psql uses directly, set those, and call "psql" directly.​

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].


​You couldn't even if you wanted to.​  Did you maybe mean the .pg_service.conf file?

You should strongly consider using .pgpass instead of "$PASSWORD" - especially depending upon where perform the export.
 

How I can modify this command with PORT option.
