<para>
Whatever you do, postmaster must be run by
the <ProductName>Postgres</ProductName> superuser (<literal>postgres</literal>?)
<emphasis>and not by root</emphasis>.
This is why all of the examples below start by switching user
(su) to postgres. These commands also take into account the fact
that environment variables like PATH and PGDATA may not be set properly.
The examples are as follows. Use them with extreme caution.
a) Edit file rc.local on NetBSD or file rc2.d on SPARC Solaris
<itemizedlist>
<listitem>
<para>
Edit file rc.local on NetBSD or file rc2.d on SPARC Solaris
2.5.1 to contain the following single line:

/usr/local/pgsql/data"
<programlisting>
su postgres -c "/usr/local/pgsql/bin/postmaster -S -D /usr/local/pgsql/data"
</programlisting>
b) In FreeBSD 2.2-RELEASE edit /usr/local/etc/rc.d/pgsql.sh to
<listitem>
<para>
In FreeBSD 2.2-RELEASE edit /usr/local/etc/rc.d/pgsql.sh to
contain the following lines and make it chmod 755 and chown
root:bin.
#!/bin/sh
[ -x /usr/local/pgsql/bin/postmaster ] && {
su -l pgsql -c 'exec /usr/local/pgsql/bin/postmaster
-D/usr/local/pgsql/data
-S -o -F > /usr/local/pgsql/errlog' &
echo -n ' pgsql'
}
<programlisting>
#!/bin/sh
[ -x /usr/local/pgsql/bin/postmaster ] && {
su -l pgsql -c 'exec /usr/local/pgsql/bin/postmaster
-D/usr/local/pgsql/data
-S -o -F > /usr/local/pgsql/errlog' &
echo -n ' pgsql'
}
</programlisting>
You may put the line breaks as shown above. The shell is smart
enough to keep parsing beyond end-of-line if there is an
expression unfinished. The exec saves one layer of shell under
the postmaster process so the parent is init. Note: Unlike most
other examples, this one has been tested.
c) In RedHat v4.0 Linux edit file /etc/inittab to add the
following single line:
pg:2345:respawn:/bin/su - postgres -c
"/usr/local/pgsql/bin/postmaster -D/usr/local/pgsql/data
>> /usr/local/pgsql/server.log 2>&1 </dev/null"
the postmaster process so the parent is init.
<listitem>
<para>
In RedHat Linux add a file <filename>/etc/rc.d/init.d/postgres.init</filename>
which is based on the example in <filename>contrib/linux/</filename>.
Then make a softlink to this file from
<filename>/etc/rc.d/rc5.d/S98postgres.init</filename>.
<listitem>
<para>
In RedHat Linux edit file /etc/inittab to add the
following as a single line:

"/usr/local/pgsql/bin/postmaster -D/usr/local/pgsql/data
&gt;&gt; /usr/local/pgsql/server.log 2&gt;&1 &lt;/dev/null"
</programlisting>
(The author of this example says this example will revive the
postmaster if it dies, but he doesn't know if there are other side
effects.)
d) The contrib/linux area of the <ProductName>Postgres</ProductName> distribution has an example
init.d script compatible with and tested using recent RedHat packages.
