otelgorm feature: pick which query variables are emitted

[igrayson]

otelgorm has the WithoutQueryVariables() option to keep the emitted statement unparameterized. I would like to emit statements that are partially parameterized. My use-case is: my service occasionally handles information which I do not want logged. On the other hand, it's really useful being able to see which IDs a database statement actually hit.

One way to satisfy this is providing something like:

func WithQueryVariableFilter(predicate func(var interface{}) bool) Option

.. and I could provide a filter that only allows uuid strings (etc)

Thoughts? I'd be happy to open a PR.

Sounds like a good idea 👍 Let's see how the code looks like.
