No problem. I hope you found them helpful.

I've found these lists very helpful in the past. Often list members
will ask for additional information to hopes of finding a solution. I
can't recall any complaints of boredom or posts wasting people's time.
I don't think you have anything to fear :) On the contrary, developers
in particular and members in general like to hear about how people are
using PostgreSQL, what they'd like to do with PostgreSQL, and what
people are doing to accomplish what they want. If you were to go into
details, you'd probably find people giving you additional help. As for
myself, I probably won't be able to help, but I'm definitely curious as
to what you're working on. Care to share? :)

What you're looking to do is much more developer level than user level.
I'm guessing you're going to get pretty deep into the code, much
further than I have any experience with. In another post, it looks like
Tom Lane pointed you towards the relevant files, or at least a place
where you can get your feet wet.

Good luck!
