I am able to reproduce the failure, I think the assert in the 'logicalrep_write_insert' is not correct. IMHO even if the replica identity is set to NOTHING we should be able to replicate INSERT? This will fix the issue. diff --git a/src/backend/replication/logical/proto.c b/src/backend/replication/logical/proto.c index dcf7c08..471461c 100644 --- a/src/backend/replication/logical/proto.c +++ b/src/backend/replication/logical/proto.c @@ -145,7 +145,8 @@ logicalrep_write_insert(StringInfo out, Relation rel, HeapTuple newtuple) Assert(rel->rd_rel->relreplident == REPLICA_IDENTITY_DEFAULT || rel->rd_rel->relreplident == REPLICA_IDENTITY_FULL || - rel->rd_rel->relreplident == REPLICA_IDENTITY_INDEX); + rel->rd_rel->relreplident == REPLICA_IDENTITY_INDEX || + rel->rd_rel->relreplident == REPLICA_IDENTITY_NOTHING); /* use Oid as relation identifier */ pq_sendint32(out, RelationGetRelid(rel)); -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com
