Yeah, you're outta luck on that one. pg_stats gained a tableid column
sometime after February, but pg_dump will try to use the column
anytime the source server reports itself as v19 or newer. There's no
provision in there for distinguishing different development versions.
I think you can get your data out by using pg_dump or pg_upgrade with
--no-statistics. In general though, keeping important data in a
development version is highly not recommended.
