pub async fn seed() -> Result<(), DBError>Expand description
Seeds the admin database (idempotent, concurrency-safe, atomic — see the
module docs and seed.sql).
After seeding, points the admin user’s db_name at this deployment’s admin
DATABASE_URL (the seed leaves it empty rather than hardcoding a
machine-specific DSN). The update is unconditional (compare-and-update on
every boot) so that if the deployment’s DSN later changes while reusing the
same admin database, the stored value tracks it rather than going stale. The
WHERE db_name <> $1 keeps it a no-op write when already correct.
§Errors
Returns DBError on a connection failure or if the seed transaction fails.
