Hi guys,

I don't want to do a patch for a one character error. Yet, that's a HUGE
error and it really needs to be fixed.

Once you have a pg_database file which is over 1 page, it CRASHES. That's
what it did on me. Yes! I have many databases or rather, I often destroy
my databases to regenerate them from scratch (that's for me the easiest
way to do it). Because of that, the pg_database is now two pages.

The utils/misc/database.c has a function called GetRawDatabaseInfo()
which reads that file "on its own". There is a HUGE bug in there, and
it may not always crash a system, but it really needs to be fixed.

At line #183, you have a for() loop which looks like this (since at
least V6.5.0 and still present in V7.0.3):

        for (i = 0; i <= max; i++)

All the other such loops start with an index of 1, not zero. And
therefore you want the <=. In this special case loop (or are all
the others special cases?!?) you need to use the following:

        for(i = 0; i < max; i++)

Please, I know it's easier when you get a patch, but FIX IT. It's
not fun to try to access your database and have the backend crash
because of such a tiny bug!

Thank you for all your work.
