That already works! :) I wrote some MySQL examples in bcc that use the MySQL USDT probe points. Eg:

https://github.com/iovisor/bcc/blob/master/examples/tracing/... https://github.com/iovisor/bcc/blob/master/examples/tracing/...

There's also a tool in /tools.

I'll whip up some PostgreSQL examples too (unless someone else beats me to it).

That looks great! (Why is char query[128] apparently unused?)

Is USDT expected to become the de facto standard for userspace probe points?

Oops, that looks like a left-over from development, that's no longer needed. Thanks! One of us should fix the example. :)
