[pgsql-www] Download page's install command (ubuntu) - Mailing list pgsql-www

Hello

There is a command to install postgresql on the download page of the official site,
If I do not add sudo, an error occured.
It may be better to add sudo before the command.

download page
https://www.postgresql.org/download/linux/ubuntu/

command
before: apt-get install postgresql-9.4
↓
after: sudo apt-get install postgresql-9.4

Thanks
