Middleware/wrapper to wrap all queries in a transaction

Feature discussion / request

I am working on automating audit logging for a Next.js application. I have a trigger function set up to run on insert/update/delete and the issue comes when trying to pass the application user's id (not the PostgreSQL user) to the trigger. I have got it working manually with the following code, but would like to be able to wrap all queries in the transaction to automate things a bit more.

    const result = await db().transaction(async (trx) => {
      await trx.raw('SET LOCAL my_app.app_session_user = ${session.user.id}')
      const insert = await trx.insert(data)
        .into('${schema}.${tableName}')
      return insert
    })

Is there currently a middleware or other method to wrap the insert query above, adding the transaction and setting the app_session_user to all queries automatically so it can be accessed in the trigger function?

Or maybe I am thinking about this all wrong, if so, any suggestions on a better method would be appreciated.
