Postgres dashboard

Mon, 01 Jan 0001 00:00:00 +0000

This builds a running dashboard over a Postgres table: rows appear when inserted, move when updated, and disappear when they stop matching — without polling and without writing any UI code. Everything comes from the published package and published plugins.

You need Docker and network access to ghcr.io.

The database

Start Postgres configured for logical replication:

docker run -d --name drasi-demo-pg \
 -e POSTGRES_PASSWORD=drasi -e POSTGRES_USER=drasi -e POSTGRES_DB=drasidemo \
 -p 5433:5432 postgres:16-alpine \
 postgres -c wal_level=logical -c max_replication_slots=8 -c max_wal_senders=8

Create the table, along with the publication the source replicates from and the replica identity that makes Postgres include the old row in updates and deletes:
