The table currently contains just over 10000 elements. So 238 rows is a

Yes. That and reindex (in case of a problem).

You mean ANALYZE VERBOSE ?
Since the table is still growing, and the amount of rows in the reply of

hope that the statistics will evolve in a state that will force the use of
the index.
