Timeout for large payload

[dthib]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

When the payload is large, it does not reach the endpoint and seems stuck in pg_net until a timeout is reached. This is the case with the latest pg_net version (0.14.0) installed by default but is not the case on one production system using 0.7.x pg_net version.

To Reproduce

With latest supabase version.
I have searched for a while but now we are sure that it's not related to our api because we were able to reproduce it with https://webhook.site.

1. Go to webhookt.site and create a endpoint
2. Execute the query below
   select * from net.http_post(
   'https://webhook.site/11a266de-f1b6-48d9-9477-3aeb8c8098cc',
   '$PAYLOAD'::jsonb)
   by replacing $PAYLOAD with the joined json payload.

3. Please note that the same query with a smaller payload is ok. Please not too that sending the payload directly to https://webhook.site using postman works too.

Expected behavior

Request beeing sent to the server

Screenshots

If applicable, add screenshots to help explain your problem.

System information

• OS: macOs
• Version of supabase postgres docker 15.8.1.020
• pg_net installed 0.14.0

Additional context

I wanted to try other pg_net versions but I can't drop & reinstall the extension as the owner is supabase_admin.
