In PostgreSQL, generate_series() can create dates, numbers, or time ranges in one line. 📅 Perfect for reports, calendars, filling data gaps! SELECT generate_series('2025-01-01', '2025-01-10', '1 day'); Result: 10-day list — no table needed! 🚀 #PostgreSQL #SQLTips #DataMagic

🚀 Too many indexes in PostgreSQL = slow INSERT/UPDATE + big disk usage 💾 ✅ Analyze with EXPLAIN (ANALYZE) ✅ Index only frequently filtered columns ✅ Find unused: SELECT * FROM pg_stat_user_indexes WHERE idx_scan=0; #PostgreSQL
