I have this patch, if you're interested.

LWLock Instrumentation Patch

- counts locks and waits in shared and exclusive mode
- for selected locks, measures wait and hold times
- for selected locks, displays a histogram of wait and hold times
- information is printed at backend exit

Configurable by #define's in lwlock.c

Regards,
pierre
