What would be the process if you need to rotate because you are switching providers(or for another reason)?
HJust swap out the IDs?
AAt some point it's probably easiest to make a new one for the new provider, and then just swap out the ID in wrangler.toml, yeah.
MHowdy! Is there any type of logging viewable for hyperdrive private database tunnels? I have a postgresql server that is connectable directly via ssh port forwarding, via the tunnel established for hyperdrive
cloudflared access tcpconst sql = postgres(env.XXXX.connectionString);
CDid anyone managed to connect a digital ocean manage postgres to a worker?
Ctried with both hyperdrive and none and it just times out, on my local it works perfectly
MYeah, that's the same issue to which I was referring in my thread yesterday (hyperdrive) - I was building a full-stack in Workers Pages and the local hyperdrive dev connection worked OK, but the hyperdrive private connection seemed to be unable to talk to the tunnel, timing out in the process. I had a very productive chat with @AJR, who is looking into the issue
AMay or may not be the same issue. Is the DO connection behind a tunnel? Or publicly accessible?
NIs there a better channel for asking questions specific to Tunnels? I'm having a connectivity issue setting up my database, but believe I've isolated it to the Tunnel.
NI followed the instructions at https://developers.cloudflare.com/hyperdrive/configuration/connect-to-private-database/ and wanted to test database connectivity, so I allowed myself through the Access Application, and am receiving connection timeout errors while trying to connect directly from pgAdmin.
Cloudflare Docs
Hyperdrive can securely connect to your private databases using Cloudflare Tunnel and Cloudflare Access.
AIf the questions are specifically about Hyperdrive through a tunnel this is the channel. Have you had a chance to look through some of the debugging points in this thread?

NI read about the logging there, and found that no logs were being generated by my connection attempts.
AOkay. If you DM me your hyperdrive ID, I'll dig a bit when I'm back in office Monday and see what I can turn up
NThank you! I'll try to do a bit more troubleshooting this weekend, and will send that over if it doesn't work.
Cpublic accessible: here you have a reproduction if it helps: pages-helpPostgres timesout on cloudflare:
I disabled hyperdrive for the reproduction, the the issue is the same (with/without hyperdrive)

JHey everyone, cross post here from the Rust channel and wondering if anyone can help.
Is anyone else using Rust alongside a Postgres database with Hyperdrive? I'm getting some weird intermittent connection issues, that is like either the worker can't connect or is timing out. I'm wondering if it's something to do with this background work happening and the connection not quite being ready.

AYes, the exograph folks are around here occasionally, and that's a good write-up. While we don't officially support extended protocol messages in tokio-postgres right now, their fork seems to work quite well for people.
MIIRC they merged this into mainline a little while ago: https://github.com/sfackler/rust-postgres/pull/1147

Introduce a new query_with_param_types method that allows to specify Postgres type parameters. This obviated the need to use prepared statements just to obtain parameter types for a query. It then ...

TWe documented how you can use Hyperdrive bindings from Pages here! 
https://developers.cloudflare.com/pages/functions/bindings/#hyperdrive-configs
Note that you will need to use Postgres.js, and set Node.js compatibility using the following configurations in your wrangler.toml
(This was mentioned in a separate thread but raising this in the main channel so all can see!)

NDoes Hyperdrive produce error logs that are visible somewhere? All I'm seeing returned to my worker is "TypeError: Cannot redefine property: query", and nothing in the Tunnel logs.
AThat's a JS error, Hyperdrive isn't throwing that one.
AExample: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Cant_redefine_property
MDN Web Docs
The JavaScript exception "can't redefine non-configurable property" occurs when it was
attempted to redefine a property, but that property is non-configurable.
attempted to redefine a property, but that property is non-configurable.
ATo answer the actual question, though, we return all errors from the origin server, plus selected Hyperdrive-specific errors, as Postgres errors to your PG client. The recommended path here is to handle errors from your driver, and either log or condition on them as needed. Logging them will have them populated with all the other Worker logs

YNew how-to configuration for Hyperdrive https://developers.cloudflare.com/hyperdrive/configuration/rotate-credentials/
Cloudflare Docs
You can change the connection information and credentials of your Hyperdrive configuration in one of two ways:
AThis is a scenario where the Postgres syntax is a bit unfortunate. SET in the context of UPDATE commands (keyword) and SET in the context of session state management (statement) are entirely unrelated, from the message protocol all the way down to the internals and back. They just happen to share the same name.
SET ROLE and such that are for session state management are going to be a problem, almost regardless of how you wrap them. We've done work to make the system more resilient, so you might get lucky, but generally I'd avoid those.
The SET keyword in the context of UPDATE statements is fine, go nuts with it.

The SET keyword in the context of UPDATE statements is fine, go nuts with it.
AI will say that the root cause of problems here is polluting state on shared/pooled connections, so if you scope that state pollution such that by the time your query resolves everything is back how it started, it seems to me that you're less likely to have problems. If you can make it work for your use case, we certainly aren't going to stop you. But it's not something we support so, y'know, we won't be able to help you much. And we do reserve the right to change things in ways that might break that workflow if we need to. Kind of "undefined behavior, in the programming languange sense" territory.
THey folks! It's great seeing all the feedback for Hyperdrive with private databases using tunnels, if you've been trying out and using it for the past few weeks, we want to learn more about your experience.
Likewise, if you've been using Hyperdrive, would love to chat 20-30 mins to better understand how you're using Hyperdrive, what are some of your asks around feature updates, how your performance has been, etc.
We have a bunch of improvements under way to improve compatibility (custom certs
) and performance and we want to make sure we're taking in your feedback! Here's my calendar -> https://calendar.app.google/b3w5dNYQj9YANw449

DHi, its there an updated timeline for MySQL support? (like early/beta/unstable access)
(MariaDB 10, 12GB database, ~ 200 Read Query/day)
tks
(MariaDB 10, 12GB database, ~ 200 Read Query/day)
tks
ANot a timeline we can share publicly yet, no.
I'll say that nobody has beta access yet, but when we get that ready we'll be asking/DMing folks. If you're interested I'll keep a note to see about reaching out to you.
We have to land custom cert support and some pretty important perf work first before we add on new features of that scale.
Also, please do hit up @thomasgauvin so he can get some details about your use case. We want to make sure that when we do ship MySQL support we don't miss features of it that a bunch of people need.

MHi! I'm trying to set up a VPS with Postgres via docker compose and then bind it in a worker via Hyperdrive.
I have followed the instructions line by line except when setting up the public hostname: instead of localhost:5432 -> postgres:5432.
When the API calls the Hyperdrive returns 504 (Gateway Timeout) to the client. To make sure the DB is working, I have tried to access the database from the VPS console through postgres:5432 and it works fine.
Any suggestions?

MHey! Seems like this has already been asked, but I wanted to ask if there's been any updates - I want to test hyperdrive with my vercel (nextjs) project. I have plans to switch to cloudflare, but don't have the bandwidth ( 
) to fix all the bugs that'll come up in the migration - yet. Either way I want to test if hyperdrive can speed up my platform by any means.

AShort answer is that this isn't something that's likely to happen any time soon. While I wouldn't close the door on it ever happening, it's not on our radar for the time being.
MOkay cool! Not an issue - is it something that would work well once I’ve deployed my next app on cloudflare?
MAs in, can I use the binding with my next app?
ASorry, which binding is that? Not sure I'm following.
