Description
</title>
<para>
<application>dropdb</application> destroys an existing
<productname>PostgreSQL</productname> database.
The user who executes this command must be a database
superuser or the owner of the database.
</para>
<para>
<application>dropdb</application> is a shell script wrapper around the
<acronym>SQL</acronym> command
<xref linkend="SQL-DROPDATABASE" endterm="SQL-DROPDATABASE-title"> via
the <productname>PostgreSQL</productname> interactive terminal
<xref linkend="APP-PSQL">. Thus, there is nothing
special about dropping databases via this or other methods. This means
that the <application>psql</application> must be found by the script and that
a database server is running at the targeted host. Also, any default
settings and environment variables available to <application>psql</application>
and the <application>libpq</application> front-end library do apply.
