-- Create 50 MUC Rooms - PostgreSQL
-- =============================================================================
--
-- Database: PostgreSQL
-- Compatibility: All PostgreSQL deployments (simple, cluster, federation, etc.)
--
-- Purpose:
--   Creates 48 additional MUC rooms (IDs 3-50) to supplement the 2 default rooms,
--   giving a total of ~50 rooms. Also redistributes any existing messages evenly
--   across all 50 rooms.
--
--   Useful for testing environments that need a moderate number of rooms with
--   message history spread across them.
--
-- Prerequisites:
--   - Rooms with IDs 1 and 2 should already exist (from 000-init-openfire.sql)
--   - Best used after generate-test-messages.sql to have messages to redistribute
--
-- Usage:
--   Option 1 - Copy to deployment's sql/ directory (runs on container start):
--
--      cp optional/sql/postgresql/create-50-rooms.sql simple/sql/002-create-50-rooms.sql
--      ./start.sh
--
--   Option 2 - Run manually against a running database:
--
--      docker exec -i simple-db-1 psql -U openfire -d openfire \
--        < optional/sql/postgresql/create-50-rooms.sql
