><P
> As with any server daemon that is accessible to the outside world,
it is advisable to run <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> under a
separate user account. This user account should only own the data
that is managed by the server, and should not be shared with other
daemons. (For example, using the user <TT
CLASS="LITERAL"
>nobody</TT
> is a bad
idea.) It is not advisable to install executables owned by this
user because compromised systems could then modify their own
binaries.
</P
><P
> To add a Unix user account to your system, look for a command
<TT
CLASS="COMMAND"
>useradd</TT
> or <TT
CLASS="COMMAND"
>adduser</TT
>. The user
name <SPAN
CLASS="SYSTEMITEM"
>postgres</SPAN

throughout this book, but you can use another name if you like.
