If the requirement is to certified the momentary condition of the page, rather than any kind of endorsement or statement on the part of the project, it might be possible to have a third-party auditor document and certify the state of the page as of a particular date. While it is clear that InDevLab is not asking for an endorsement from the project, any official from the project can be interpreted that way.

This seems to amount to a policy of proving a negative - that no other competitive vendors exist thus permitting an alternative acquisition process. Seems like whomever is asking for this evidence should be the one saying that another vendor exists and therfore both you and them need to abide by the normal process.
The absebce of any other companies on the website is not itself evidence of non-existence.
If you want something a bit more conclusive I’d ask on the -general mailing list whether anyone knows of any such companies besides those listed at the aforementioned web page. Those emails are archived, publicly accessible, and timestamped. It provides a better attempt at proving the negative than your original request.

Hi Max,
The professional services listing page is only a listing, not an endorsement of services[1]. Further, the PostgreSQL trademark policy[2] prevents organizations from officially claiming endorsement from the PostgreSQL community. Unfortunately, we can't provide this requested letter.

Therefore, we would be extremely grateful if you could provide us with a formal letter or an official email confirming a simple, verifiable fact: /that as of the current date, InDevLab LLC is the only company listed under the 'Ukraine' section on the Professional Support page of the postgresql.org website./
