Same issue for the first 4 errors here

Denodb is apunting to version 0.4.3, with is in denopage:

deno.land / x / denodb@v1.0.8 / deps.ts
export { Client as PostgresClient } from "https://deno.land/x/postgres/mod.ts";

If we using that we are apunting to 0.4.3 version
https://deno.land/x/postgres@v0.4.3/connection.ts#L613

If you wanna solve this you could clone, with has 0.4.4 version and change postgres/mod.ts for that repository.

Hey,

Thanks for raising this issue.

@lazcanocode 0.4.4 is not available on deno.land yet, only on Github at the moment. Are you sure 0.4.4 fixes the issue?
If so, we can update the dependencies to use Github source instead.

Just let me know so I can take this forward.

Keep in touch

Just a quick update: it seems like 0.4.4 fixes the issue indeed (@lazcanocode is correct!).

People raised the issue that the release was not published on deno.land already (denodrivers/postgres#169).

I will just wait on that to be solved for now, let's be patient!

Hi,

This is easily forked to work but i'm thinking about the future of these kind of situations. It's not so convenient to create a fork for just one line. Is there any way to override dep(s) inside your App just to get rid of them if there is an update to the original?

This should now be fixed by #113, thanks to @ThomasT404.

Feel free to comment again if anything else comes out :)
