PostgreSQL 15 on Debian, both ends of replication. I'm doing logical replication in a bit of a complex setup. Not sure how much of this is relevant so I'll give you a lot of detail; sorry if a lot of this is just noise. * Bidirectional alternating-master replication. Since I'm still on PG 15, the replication is up in one direction, down in the other, rather than actually being simultaneous. * Replication is defined as "for all tables". All relevant tables are in a single schema, "stillebot". * Replication was working fine on initial deployment, including a swap of master/slave. * One table was created without a primary key, and subsequently altered to have "replica identity full". * Replication is not working for this table (stillebot.settings) but is working for other tables. I tried restarting Postgres on the slave and monitoring /var/log/postgresql/postgresql-15-main.log and it all seemed happy. According to pg_subscription_rel, all tables are in their "replication" phase: select srsubstate,srsublsn,relname from pg_subscription_rel join pg_class on srrelid=oid; srsubstate | srsublsn | relname ------------+----------+-------------------------- r | | user_followed_categories r | | config r | | config_exportable r | | commands r | | settings (5 rows) If I make a change to user_followed_categories, it works fine. If I make a change to settings, it does not replicate. The stillebot.config table seems somewhat desynchronized - rows are missing - but if I INSERT a new row into it, it gets properly replicated. How can I dig into this to determine what's going on? Have I broken things by creating a table without a primary key? (It's a singleton table, will only ever have one row in it; could add a meaningless PK if it helps the replication.) Are there other logs to inspect? Thanks in advance! ChrisA
