Looks to me like you've got some serious problems with corruption of the
system tables :-(
If you can SELECT from the tables you need, I'd suggest dumping out
their contents using COPY commands. Then you can reload those data
files into a newer database (assuming you remember what the table
schemas were). 6.5.2 is old enough that I don't really remember how
to do any sort of data-recovery work with it...
