Re: [BUGS] possible database corruption

Try applying the following patch, which corresponds to a bug that I
noticed in GetRawDatabaseInfo a couple months ago: it looks at one
tuple-pointer slot too many in each page of pg_database.  Normally the
bogus slot will be ignored because it doesn't have the LP_USED bit set,
but if you create and drop databases a lot, it's possible there would
be garbage there.

If this doesn't help, please recompile the backend with -g, so that we
can see a more detailed stack backtrace.
