<DT><STRONG>ERROR: user '<EM>username</EM> ' is not allowed to create/drop databases</STRONG>
<DD>You
must have the special CREATEDB privilege to drop databases. See <EM>CREATE
USER</EM>.
<DT><STRONG>ERROR: dropdb: cannot be executed on the template database</STRONG>
<DD>The
template1 database cannot be removed. It's not in your interest.
<DT><STRONG>ERROR: dropdb: cannot be executed on an open database</STRONG>
<DD>You
cannot be connected to the database your are about to remove. Instead,
you could connect to template1 or any other database and run this
command again.
<DT><STRONG>ERROR: dropdb: database '<EM>name</EM> ' does not exist</STRONG>
<DD>This
message occurs if the specified database does not exist.
<DT><STRONG>ERROR: dropdb: database '<EM>name</EM> ' is not owned by you</STRONG>
<DD>You
must be the owner of the database. Being the owner usually means that
you created it as well.
<DT><STRONG>ERROR: dropdb: May not be called in a transaction block.</STRONG>
<DD>You
must finish the transaction in progress before you can call this command.
<DT><STRONG>NOTICE: The database directory 'xxx' could not be removed.</STRONG>
<DD>The
database was dropped (unless other error messages came up), but the
directory where the data is stored could not be removed. You must
delete it manually.

<P>
<B>DROP DATABASE</B> removes the catalog entries for an existing
database and deletes the directory containing the data. It can only
be executed by the database owner (usually the user that created it).

Notes </A>
</H3>
<P>
This command cannot be executed while connected to the target database.
Thus, it might be more convenient to use the shell script dropdb,
which is a wrapper around this command, instead.
<P>
Refer to <EM>CREATE DATABASE</EM> for information on how to create a
database.
