| Tiktok | The Stack: PostgreSQL. Most people poll it on a timer to notice a change. Instead, use built-in LISTEN and NOTIFY. Your app reacts the second an order lands, no wasted queries. Add one NOTIFY trigger and listen. (AI-assisted) |
| The Stack: PostgreSQL. Stop polling on a timer. Use LISTEN / NOTIFY. React the second a row changes. Zero wasted queries. Add one trigger to start. #postgresql #database #backend #devtools #thestack | |
| The Stack: PostgreSQL, the database that quietly runs the world. The common limit: most people poll it on a timer to notice a change. That means wasted queries hammering the database every minute. Instead, use Postgres's built-in LISTEN and NOTIFY. Your app reacts the second an order lands or a status flips, with no polling. The move: add a NOTIFY trigger to one table and listen for it. Start with the table you poll the most. | |

| This week in The Stack: PostgreSQL. Most people poll it on a timer to catch a change, which wastes queries every minute. Instead, use the built-in LISTEN and NOTIFY so your app reacts the second a row changes. Start by adding one NOTIFY trigger to a single table. More at temerarii.xyz. | |
| Threads | The Stack: PostgreSQL. The limit most people hit: polling it on a timer to notice a change, which hammers the database with wasted queries. Use built-in LISTEN and NOTIFY instead. Your app reacts the second an order lands or a status flips. Add a NOTIFY trigger to one table and listen. |
| PostgreSQL developer tip: replace timer-based polling with the built-in LISTEN and NOTIFY commands for event-driven updates. Your application reacts the instant a row changes, with zero wasted queries. Add a NOTIFY trigger to one table and listen for it. Practical Postgres backend pattern. | |
| Bluesky | The Stack: PostgreSQL. Stop polling on a timer. Use built-in LISTEN/NOTIFY so your app reacts the instant a row changes. Add one NOTIFY trigger and listen. |
| Youtube | Title: PostgreSQL LISTEN/NOTIFY: Stop Polling Your Database Most teams poll PostgreSQL on a timer to catch changes, wasting queries every minute. This shows the event-driven alternative: Postgres's built-in LISTEN and NOTIFY, so your app reacts the second an order lands or a status flips. The move is to add one NOTIFY trigger and listen for it. More at temerarii.xyz. |
