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" endterm="APP-PSQL-title">. 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.

Usage
</title>
<para>
To destroy the database <literal>demo</literal>
on the default database server:
<programlisting>

</para>
<para>
To destroy the database <literal>demo</literal>
using the postmaster on host eden, port 5000, with verification
and a peek at the underlying query:
<programlisting>
$ <userinput>dropdb -p 5000 -h eden -i -e demo</userinput>
Database "demo" will be permanently deleted.
Are you sure? (y/n) <userinput>y</userinput>
QUERY: DROP DATABASE "demo"
