pgrstFormat :: Status -> OutputFormatter

Log in apache format. Only requests that have a status greater than minStatus are logged. | There's no way to filter logs in the apache format on wai-extra: https://hackage.haskell.org/package/wai-extra-3.0.29.2/docs/Network-Wai-Middleware-RequestLogger.html#t:OutputFormat. | So here we copy wai-logger apacheLogStr function: https://github.com/kazu-yamamoto/logger/blob/a4f51b909a099c51af7a3f75cf16e19a06f9e257/wai-logger/Network/Wai/Logger/Apache.hs#L45 | TODO: Add the ability to filter apache logs on wai-extra and remove this function.
