Improve installation instructions with pg_ctl in documentation

michaelpq · michaelpq · commit 3e938a83b2ee · 2019-02-02T13:23:26.000+09:00
The documentation includes sections to be able to initialize and start
Postgres via a couple of commands.  Some of its recommendations involve
using directly "postgres", which is inconsistent with the recommendation
given by initdb.  At the same time make some other command calls more
consistent with the rest, by using an absolute path when creating a
database.

      The previous <command>initdb</command> step should have told you how to
      start up the database server. Do so now. The command should look
      something like:
-<programlisting>/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data</programlisting>
-     This will start the server in the foreground. To put the server
-     in the background use something like:
-<programlisting>nohup /usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data \
-    &lt;/dev/null &gt;&gt;server.log 2&gt;&amp;1 &lt;/dev/null &amp;</programlisting>
