Connect to Postgres

How to connect to the postgresql cluster as a superuser using psql.

Prerequisites

  • psql installed (brew install libpq on macOS)
  • 1Password CLI (op) installed and signed in
  • Machine on the tailnet (e.g. gilbert)

Connect

PGPASSWORD=$(op read "op://blumeops/postgres/password") psql -h pg.ops.eblu.me -U eblume -d postgres

This connects as the eblume superuser. To connect to a specific database, replace postgres with the database name (e.g. miniflux, teslamate).
