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=# \l
List of databases
Name | Owner | Encoding | Collation | Ctype | Access
Privileges

bench | postgres | SQL_ASCII | C | C |
postgres | postgres | SQL_ASCII | C | C |
template0 | postgres | SQL_ASCII | C | C |

template1 | postgres | SQL_ASCII | C | C |

(4 rows)
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:
