Hack or review PostgreSQL replication internals — covers physical streaming, archive shipping, logical decoding, logical replication PUB/SUB, and synchronous-commit machinery. Names walsender / walreceiver / replication slot / output plugin callbacks plus the relevant GUCs (wal_level, max_wal_senders, max_replication_slots, max_logical_replication_workers, primary_conninfo, primary_slot_name, synchronous_standby_names) and the source files behind each flavor. Use whenever a PG patch touches walsender, walreceiver, replication slots, logical decoding, output plugins, publications/subscriptions, conflict detection, sync replication, failover slots, pg_basebackup, or pg_receivewal — or when picking which mechanism fits a feature design. Skip for MySQL row-based / GTID replication, MongoDB replica sets, Cassandra hinted handoff, Kafka MirrorMaker / Confluent Replicator, Debezium / Flink CDC pipelines, AWS DMS, and Galera / Group Replication.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
