Describe the bug

Trying out various solutions from this issues thread, nothing consistently works

e.g. #1040 or #node ace db:truncate throws the error deadlock detected #1027

import db from '@adonisjs/lucid/services/db'
/**
 * Truncate all tables except AdonisJS system tables
 * to ensure a clean state for tests
 */
export async function truncateTablesExceptAdonis() {
  // Get all table names
  const tables = await db.rawQuery(
    "SELECT tablename FROM pg_tables WHERE schemaname = 'public' AND tablename NOT LIKE 'adonis_%'"
  )
  const trx = await db.transaction()

  // Disable foreign key checks temporarily
  try {
    await trx.rawQuery('SET session_replication_role = replica;')
    await trx.rawQuery('SET CONSTRAINTS ALL DEFERRED;')
    // Truncate each table
    const tablesToTrunacte = tables.rows.map((row) => row.tablename)

    await trx.rawQuery(`TRUNCATE ${tablesToTrunacte.join(',')} RESTART IDENTITY CASCADE;;`)
    // Re-enable foreign key checks
    await trx.rawQuery('SET session_replication_role = DEFAULT;')
    await trx.rawQuery('SET CONSTRAINTS ALL IMMEDIATE;')

    await trx.commit()
  } catch (error) {
    await trx.rollback()
  }
}
