(#10359 ) The postgres statistics collector sometimes massively underestimates the number of distinct state groups are in the `state_groups_state`, which can cause postgres to use table scans for queries for multiple state groups. We fix this by manually setting `n_distinct` on the column.	2021-07-15 16:02:12 +01:00

Reduce likelihood of Postgres table scanning `state_groups_state`. (#10359 )

The postgres statistics collector sometimes massively underestimates the
number of distinct state groups are in the `state_groups_state`, which
can cause postgres to use table scans for queries for multiple state
groups.

We fix this by manually setting `n_distinct` on the column.
