To enable PostgreSQL, add the following to your
|
|
<filename>configuration.nix</filename>:
|
|
<programlisting>
|
|
<xref linkend="opt-services.postgresql.enable"/> = true;
|
|
<xref linkend="opt-services.postgresql.package"/> = pkgs.postgresql_9_4;
|
|
</programlisting>
|
|
Note that you are required to specify the desired version of PostgreSQL
|
|
(e.g. <literal>pkgs.postgresql_9_4</literal>). Since upgrading your
|
|
PostgreSQL version requires a database dump and reload (see below), NixOS
|
|
cannot provide a default value for
|
|
<xref linkend="opt-services.postgresql.package"/> such as the most recent
|
|
release of PostgreSQL.

<!--
|
|
<para>After running <command>nixos-rebuild</command>, you can verify

By default, PostgreSQL stores its databases in
|
|
<filename>/var/db/postgresql</filename>. You can override this using
|
|
<xref linkend="opt-services.postgresql.dataDir"/>, e.g.
|
|
<programlisting>
|
|
<xref linkend="opt-services.postgresql.dataDir"/> = "/data/postgresql";
|
|
</programlisting>
