My application, when encountering a database-related error, logs it as follows:

19:30:04.994 request_id=F4COjwtYrfbnTSkAABcx [debug] QUERY ERROR source="table_xyz" db=0.0ms queue=18.5ms idle=287.9ms SELECT ... FROM ... WHERE ... [1]
19:30:04.994 request_id=F4COjwtYrfbnTSkAABcx [info] Sent 500 in 81ms
19:30:04.994 request_id=F4COjwtYrfbnTSkAABcx [debug] Converted error Postgrex.Error to 500 response

This is eminently unhelpful – for one, this shouldn’t be debug level, but more importantly, it doesn’t show any information about the error itself that would allow me to fix it.

As far as I know, my logger configuration is limited to

config :logger, :console,
  format: "$time $metadata[$level] $message\n",
  metadata: [:request_id]

I’m not sure what else I may have misconfigured to cause this problem, and would be grateful for any ideas where to look next.
