Changed error message for blocks by prepared transactions

Hello,

the small attached patch changes the error message for a blocked
database in case there are prepared transactions. The original message
"accessed by other users" is misleading.

Example:

----- snip -----
postgres=# begin;
BEGIN
postgres=# prepare transaction 'abc';
PREPARE TRANSACTION
postgres=# \c template1
psql (8.4rc1)
Sie sind jetzt verbunden mit der Datenbank »template1«.
template1=# alter database postgres rename to test;
ERROR: database "postgres" is being blocked by prepared transactions
DETAIL: There are 1 prepared transaction(s) using the database.
----- snip -----

Translation still pending, how to add new messages to the .po files?

Kind regards
