Action Steps
  1. Install pg_partman extension using SQL command: CREATE EXTENSION IF NOT EXISTS pg_partman
  2. Configure partitioning for a large table using pg_partman functions: partman.create_parent() and partman.create_partition()
  3. Schedule partition maintenance tasks using pg_cron: SELECT cron.schedule()
  4. Run a sample query to test partitioning performance: EXPLAIN ANALYZE SELECT * FROM large_table
  5. Monitor and optimize partitioning configuration as needed: ANALYZE large_table; VACUUM large_table
