Joshen Lim 5b301e1ffa Add docs for diagnosing stuck and blocked queries (#48920)
## Context

Related to the dashboard work for [Database
Connections](https://github.com/orgs/supabase/discussions/48639) -
updates the "Connection Management" docs page to include a section about
"Diagnosing stuck and blocked queries". Content is intentionally
agnostic to the UI, but more focused on Postgres.

Preview:
https://docs-cdukolvgy-supabase.vercel.app/docs/guides/database/connection-management

Covers the following sub-topics:
- Reading a session's state
- Finding out what's blocking a query
- How to stop the session responsible
- Small footer to link to the dashboard's Database Connections page

Also adding a cross-reference in 2 areas
- Troubleshooting: How to check if my queries are being blocked by other
queries
- Monitoring and Debugging MDX -> Related to observability skills

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
