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

🚀 Slow pagination with OFFSET? ✅ Use WHERE id > last_id instead ✅ Speed up with an index sqlCopyEditSELECT * FROM t WHERE id>100 LIMIT 50; 💡 Huge improvement on large datasets! #PostgreSQL

🚀 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

⚡ Slow PostgreSQL? The culprit might be Seq Scan! ✅ Update stats with ANALYZE ✅ Try SET enable_seqscan = off to test index ✅ Check plan via EXPLAIN (ANALYZE) 💡 Seq Scan can be fastest for small tables. #PostgreSQL #SQLTips
