Given the size of the other columns in this table - in particular the config JSON column - saving some characters with those abbreviations does not feel worth it. It just makes things harder to debug.

Manual migration script:

sqlite-utils content.db "UPDATE _enrichment_jobs
SET status = CASE
                WHEN status = 'p' THEN 'pending'
                WHEN status = 'f' THEN 'finished'
             END
WHERE status IN ('p', 'f');"
