There is also a superuser "postgres" and an unprivileged user "smith"
you should be able to login with.  You could also start postgres in
single-user mode to bypass the authentication altogether.

Ok, I'll do testing with the patch applied.

Btw, I also find entries like following in the logging database:

ERROR:  could not read block 2638 in file "base/16384/17256": read only 0 of 
8192 bytes

…with relfilenode being an hash index.  I usually ignore these as they
naturally start occuring after a recovery because of an unrelated crash.
But since 11003eb, they also occur when the cluster has not yet suffered
a crash.
