I have CC'ed this over to advocacy in hopes that someone will be able to
get support for this work. Please email Oleg if you can financially
assist.

Hi there,

I want to inform that we began to work on concurrency and recovery
support in GiST on our's own account and hope to be ready before 8.1
code freeze. There was some noise about possible sponsoring of our work,
but we didn't get any offering yet, so we're looking for sponsorhip !

We recognize that current GiST doesn't conform to enterprize level and
our people starting experience difficulties using our extensions in
production environment. That's why we decided to meet the wishes of
GiST users not waiting real sponsorship.

Our plan is to implement recovery first because we'll use LSN as NSN
(node sequence number) needed for concurrency.

We had a lot of interest in sponsoring this before, can we get support
up again? How do we fundraise for this feature? Can we set up some
sort of paypal thing on postgresql.org? I for one am willing to donate
some of the proceeds of some current paid phpPgAdmin work (assuming the
other devs don't mind :) )

There is a couple of ways to do it. Paypal IMHO is not the way. One
way would be to set up an escrow that was tied to specific milestones.
Another would be to have an entity actually be the distribution point.

That entity can be a corporation such as Command Prompt or even just a
trust through an attorney.

However it is good to have some level of entity do it because if you get
commercial backing the companies can right off the money as outside
services and actually receive an invoice etc...

I have acted as a go-between before in this capacity. I do not
recommend a company in that role.

In some cases it can be easier for a company when another company
is involved because then there's someone who can deal with all
the accounts payable & international money transfer stuff that
would make my current CFO cringe.

The guys that run PostGIS are contributing $2000 themselves
and are willing to handle some of that paperwork for
companies that want it.

But yeah, in general I agree with Bruce that other than
corporate paperwork reasons I'd rather go directly (with something
like paypal) or through at least through the dev team.

Sure and I don't argue that except for the reasons that you have already
mentioned ;).

However I wouldn't use paypal. If you really want to use an intermediary
like that, use www.escrow.com or something.

It's very nice news ! In turn, I can say GiST recovery just passes first test.

I have account in citibank :), so I could accept money transfer. Please note,
no checks !
