Does anyone face this error when updating the liquibase version to 4.23.1 from 4.5.0?  
My spring-boot version is pointed to 3.1.2 and I am using databasechangelog.yaml file as config for liquibase

Caused by: liquibase.exception.DatabaseException: liquibase.exception.DatabaseException: ERROR: cannot update table “databasechangelog” because it does not have a replica identity and publishes updates  
Hint: To enable updating the table, set REPLICA IDENTITY using ALTER TABLE. [Failed SQL: (0) UPDATE {schemaName}.databasechangelog SET MD5SUM = NULL]

Hello @ponnatd ! Seems this error is not related to liquibase but it is a Postgresql configuration ([PostgreSQL: Documentation: 12: 30.1.&nbsp;Publication](https://www.postgresql.org/docs/12/logical-replication-publication.html)) . The easier solution would be to run the following sql:

```auto
ALTER TABLE databasechangelog REPLICA IDENTITY FULL;

```
