Fine with me. There are now some really good tracing tools available to
help out these days, and I think the PostgreSQL guys went with systemtap
in the end.

The benefit of using the same tracing mechanism across PostgreSQL and
PostGIS is that you can enable tracepoints across both projects as
required at runtime without needed to recompile.
