Thanks for the reply. I deleted all rows in pg_statistic and the VACUUM ANALYZE on pg_attribute still fails. I tried
toreindex pg_toast_2619 and got an error "could not access status of transaction 1493786085. Could not open file
"pg_subtrans/5909":No such file or directory. Sure enough, there is no such file - only 5905.

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 ...
