Clear CPanel cache of Postgres databases?

Hello.

I'm running into a problem where CPanel thinks a postgres database exists when it really doesn't. The database is listed in CPanel with a size of 0.00MB. Trying to delete it from CPanel results in a postgresql error (since the database doesn't actually exist). Trying to re-create the database with the same name causes a CPanel error since it thinks the database exists already (when it really doesn't).

Does cpanel have some internal cache of postgresql databases? If so, how can I delete the cache? I cannot find any option to do this in WHM.

(I tried deleting the ~/.cpanel/datastore/postgres-db-count and ~/.cpanel/datastore/pg_info.db files, but they just get recreated again with wrong info.)

Thanks.

Hello :)

Do you notice any particular error messages in /usr/local/cpanel/logs/error_log when attempting to delete the database?

Thank you.

Here's the error I see in the CPanel web interface when trying to delete the non-existent database:

Code:
Deleted the database xxx_yyy [a fatal error or timeout occurred while processing this directive] Postgres query failed: DROP DATABASE "xxx_yyy";: DBD::PgPP::db do failed: ERROR: database "xxx_yyy" does not exist Failed to drop database “xxx_yyy,” with error “ERROR: database "xxx_yyy" does not exist ”
/usr/local/cpanel/logs/error_log contains the following relevant lines (I would have attached this as a text file, but the "Manage Attachments" button isn't working :( ):

Code:

Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

Support responded.

There's cache/config of databases in /var/cpanel/databases/

I did the following to fix my problem:

Delete: /var/cpanel/databases/<username>.cache
Edit this to remove the database from the list: /var/cpanel/databases/<username>.yaml
