Description

</TITLE>
|
|
<PARA>
|
|
<application>destroydb</application> destroys an existing
|
|
<productname>Postgres</productname> database.
|
|
The person who executes this command must be
|
|
the database administrator, or <acronym>DBA</acronym>,
|
|
or must be the <productname>Postgres</productname> super-user.
|
|
The program runs silently; no confirmation message will be displayed.
|
|
After the database is destroyed, a Unix shell prompt will reappear.
|
|
|
|
<para>
|
|
All references to
|
|
the database are removed, including the directory containing this
|
|
database and its associated files.
|
|
|
|
<para>
|
|
<application>destroydb</application> is a shell script that invokes
|
|
<application>psql</application>.
|
|
Hence, a <application>postmaster</application>
|
|
process must be running on the database server host before
|
|
<application>destroydb</application>
|
|
is executed. The
|
|
<envar>PGOPTION</envar>
|
|
and
|
|
<envar>PGREALM</envar>

environment variables will be passed on to

and processed as described in <xref linkend="app-psql" endterm="psql-ref">.
