It's corrupt, but fortunately for you, 2619 is pg_statistic which is
eminently discardable data. Just truncate pg_statistic and you should
be good. If you aren't immediately abandoning the old database, you
might want to re-ANALYZE everything to reconstruct the stats.
We've seen one or two reports like this before, which makes me think
there might be a reproducible bug lurking somewhere around here; but
I don't suppose you have a recipe for getting a database into this
state ...
