I'm guessing you have some sort of data-corruption problem in the system
catalogs, probably in pg_class. Do you get a similar error if you say
"SELECT * FROM pg_class"? If so, try to narrow down exactly which value
causes the problem --- for instance, try selecting one column at a time
to see which column the trouble is in.

Of course you know you should be running something newer ;-). But a
quick look through the CVS logs does not reveal anything that looks
related in later 7.2.* fixes, so an in-place update probably won't
solve your immediate problem.
