facebookThis 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.

pinterestPostgreSQL 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.

youtubeTitle: 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.
