# How do I update connection pool settings in my dashboard?

Common questions about updating settings for PgBouncer or Supavisor:

- How to tell which connection pooler you're using:
  The PgBouncer connection string looks like: `postgres://postgres:[YOUR-PASSWORD]@db.xxxxxxxxxx.supabase.co:6543/postgres`

The Supavisor connection string looks like: `postgres://postgres.xxxxxxxxx:[YOUR-PASSWORD]@aws-0-us-west-1.pooler.supabase.com:6543/postgres`

The subdomain will vary depending on the region a project is deployed in. The project reference is to be included in the username following a `.`. If the username is `postgres` the username you use for Supavisor is `postgres.[PROJECT_REF]`.

- How to update the size of the connection pool to the database:
  You can set the `Max Client Connections` field in your database settings here:

- How to change the client connection limit:
  You can set the `Default Pool Size` field in your database settings:

- How to use `session` mode:
  With Supavisor you can automatically use `session` mode by using the connection string with port `5432` in it.

You can also set the pooler port 6543 to use `session` mode in the database settings:
