Summary
Triggered by powersync-ja/powersync-service#607, which improved diagnostics for Postgres replication slot health: WAL budget warnings now surface in the Diagnostics API when remaining budget drops to 50% or below, and error messages for invalidated slots include explicit recovery steps.
Changes
maintenance-ops/self-hosting/diagnostics): Added documentation for the Diagnostics API response format including WAL-related fields (wal_status,safe_wal_size,max_slot_wal_keep_size), WAL budget warnings, and replication lag warnings.configuration/source-db/postgres-maintenance): Added a new "Recovering from an invalidated slot" section with step-by-step recovery instructions for when a replication slot's WAL status islost.
