Adam -

Is compiling postmaster with profiling support just a flag
in the build/make? Or is there something more involved?

I'd like to be able to do this in the future and so am
curious about means/methods.

If this is a RTFM, just let me know that (am currently
Reading The F Manual), but if you have any "special sauce"
here, that'd be of great interest.

Thanks

-Ross

Subject: [PERFORM] Tweaking a C Function I wrote

I wanted to see if I could squeeze any more performance out of a C set
returning function I wrote. As such, I looked to a profiler. Is it
possible to get profile information on the function I wrote? I've got
postmaster and my function compiled with profiling support, and can find
the gmon.out files... can I actually look at the call tree that occurs
when my function is being executed or will I be limited to viewing calls
to functions in the postmaster binary?
