Yup that's it. But this project uses (ugh) Hibernate. I can't change
it. I may have to change
from BIGINT primary keys to INT.

Also:
Any hints on the table statistics? I turn them on, in a session, as
user postgres, but get nothing:

stage=# SHOW ALL;
name | setting
--------------------------------+----------------
...
stats_block_level | on
stats_command_string | on
stats_reset_on_server_start | on
stats_row_level | on
stats_start_collector | on

stage=# select * from pg_statio_user_indexes;
relid | indexrelid | schemaname | relname
| indexrelname | idx_blks_read | idx_blks_hit
----------+------------+------------+-----------------------------+----------------------------------+---------------+--------------
