Sorry, I don't think this would be a good fit for puddle. puddle avoids external dependencies and this brings in the github.com/prometheus/client_golang. If there was a non-invasive approach to allowing instrumentation or external metrics, I would consider it. But the primary goal for puddle is stability and the bar is really high for changes. See https://github.com/jackc/puddle#status. |

Hello,
I think it might be useful to have an acquire duration histogram, so I added one :)
Histogram is optional, one can enable it with options. Approach is inspired by prom grpc middleware.
Let me know if any changes are needed for this PR to be accepted, I am open for discussion.
Also please let me know if there's no intend to add such histogram support at all.
