It's presumably dependent on the contents of pg_statistic and the
relpages/reltuples counts in pg_class for the tables involved.
You could likely reproduce it by migrating that data to your laptop.
It would take a little bit of hacking to get the pg_statistic data
in (adjusting starelid for instance) but I think it's doable.

Note that the planner control settings (eg effective_cache_size) might
also need to be copied.
