Browse source

made from (assuming a `log_line_prefix` that includes `%a` in the
postgres configuration).

description = ''
The DBI string for Hydra database connection.
NOTE: Attempts to set `application_name` will be overridden by
`hydra-TYPE` (where TYPE is e.g. `evaluator`, `queue-runner`,
etc.) in all hydra services to more easily distinguish where
queries are coming from.
