Sounds like some bad data has gotten into your pg_statistic table.
You can probably fix the problem by running VACUUM ANALYZE.

What Postgres version are you running?  I recall hearing of someone
seeing that error with a buggy pre-alpha version, but not with any
production releases...

VACUUM ANALYZE your table.  6.4 has problems with ALTER TABLE ADD COLUMN
and Alpha cpus.
