How to make Drupal 8 forget an old deleted field? After deploying a Drupal 8 site to a new server, we have the problem of an old deleted field being remembered by some subsystem or other, leading to this error being thrown on whenever cron runs:

Drupal\Core\Database\DatabaseExceptionWrapper:
SQLSTATE[42S02]: Base table or view not found:
1146 Table 'drupal8_neu_default.field_deleted_data_1c89727af8' doesn't exist:
SELECT DISTINCT t.entity_id AS entity_id
FROM {field_deleted_data_1c89727af8} t
WHERE  (bundle = :db_condition_placeholder_0)
LIMIT 50 OFFSET 0; Array
(
    [:db_condition_placeholder_0] =&gt; video
)
in
Drupal\Core\Entity\Sql\SqlContentEntityStorage-&gt;readFieldItemsToPurge()
(line 1546 of /srv/www/neu.default.ch/builds/v1.0.0-alpha.7/docroot/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).


I've spelunked all over the database, and I can't figure out where to expunge the reference to this long-dead table. It's not mentioned in config and the field_config table we knew from Drupal 7 is long gone. It's also not in the exported configuration.

Does anyone know how to fix this?
Execute this to remove deleted field(s), pending deletion:

drush php-eval 'field_purge_batch(1000);'
