PITR failing to stop before DROP DATABASE

In 9.3.5, if I set up archiving, create a database, pull a base
backup, look at the clock, drop database, stop the server, rm -rf
datadir, put back the backup, edit recovery.conf:

cd /tmp; initdb foo
edit postgresql.conf with archive_mode = on, archive_command,
max_wal_senders = 1, wal_level = hot_standby
edit pg_hba.conf
pg_ctl start
psql -c 'create database db1'
psql -c 'checkpoint'
pg_basebackup -D /tmp/back1
date
Di 25. Nov 17:00:31 CET 2014
psql -c 'drop database db1'
pg_ctl stop
rm -rf foo; cp -a back1 foo

restore_command = 'cp /tmp/%f %p'
standby_mode = on
recovery_target_time = '2014-11-25 17:00:31'

... and then restart the server, I get:

postgres=# \c db1
FATAL: database "db1" does not exist
DETAIL: The database subdirectory "base/70262" is missing.

db1 is registered in pg_database, but the directory is missing on
disk.

(The actual log here is from a server with a longer history, but the
problem is reproducible in a freshly initdb'ed server as well.)
