request for wiki editor access

Hello.

I would like editor access to the wiki, my username is 'gregburd' and I would like to modify a few pages:
* https://wiki.postgresql.org/wiki/Multithreading
* https://wiki.postgresql.org/wiki/Partial_Heap_Only_Tuples

and likely more over time.

For multi-threading I want try to drive this project forward, it's larger than a single person so somehow the community needs a way to coordinate. If there's already a way to do this that I don't know of, please inform me! :)

For PHOT, well I've been working on resurrecting that for a while now with Nathan. We'd/I'd like to update the page to reflect the status/design/etc.

I'm sure there's more I'd like to edit... but I'll start there.

thanks!
