Hot standby v5 patch - Databases created post backup remain inaccessible + replica SIGSEGV when coming out of standby

Another corner case:

1/ Setup master and replica with replica using pg_standby
2/ Create a new database (I used 'bench')
3/ Initialize the pgbench schema of size 100 in 'bench' (just to ensure 
the logs with the db creation get archived)
3/ Attempt to connect to 'bench' on the replica

Head from 2nd Nov with v5 patch applied on Freebsd 7.1-Prerelease as 
usual....

postgres=# \c bench
FATAL:  database "bench" does not exist
Previous connection kept


Not sure if this is related at all, but if the replica is then 
instructed to finish recovery via touching its trigger file, then we get:
