Hmph. Apparently there is something wrong with the pg_internal.init
file in this database.

That was premature --- you could have just removed the broken init file
(which is merely a cache). I'm not sure how easy it'll be to identify
the problem with the cache file without an easy way to compare to valid
data, but if you want to send me the saved-off init file I'll take a
look. Which PG version is this again?
