Describe the Bug

Hyperdrive does not seem to support SSL, when connecting to a public database.

I'm using Neon, Drizzle and the URL postgresql://user:pass@host.aws.neon.tech/neondb?sslmode=require&channel_binding=require

However, whenever I try to run a query, the code throws error: connection is insecure (try using sslmode=require)

I did try:

Set WRANGLER_HYPERDRIVE_LOCAL_CONNECTION_STRING_HYPERDRIVE in .env -> Doesn't work
Set localConnectionString in the json config -> Doesn't work

Please provide any relevant error logs

This makes hyperdrive unusable for me, because developing with --remote flag is not doable, lot of ping and no local debugger. It should be the first thing they at Neon website when using Hyperdrive. The have it at the very end as if not important "oh btw you cannot work locally if you use it"

This issue makes it impossible for the local environment to match the server's environment exactly, which is unfortunate.

I have shared it with the internal team and track it in SQC-645.

We're aware of this issue and are considering approaches to make it possible to connect to a remote database. Note that the earliest timeline is in 2026 due to changes needed in workerd and Workers runtime

for anyone still on the issue, so far the "fix" has been to use a conditional variable, on dev/test mode I'm using a direct connection to the postgres instance, eg:

const url = env.isLocal ? env.DB_URL : env.HYPERDRIVE.connectionString
const client = postgres(url, {
  fetch_types: false,
  max: 2,
});
