I'd like to use Liquibase, is it possible to make those things work together? 回答1: You have two options

问题 We have SpringBoot 2 driven HA java application in which we use PostgreSQL underneath. For certain reasons like unexpected crashes or Exceptions, Liquibase ends up with a stale DATABASECHANGELOGLOCK which was never released. This results in subsequent deployments of the app failing with app waiting for the change lock and then exiting as follows: 2020-03-04T11:10:31.78+0200 SELECT LOCKED FROM public.databasechangeloglock WHERE ID=1 2020-03-04T11:10:31.78+0200 Waiting for changelog lock....

问题 I use postgres DB, I faced an issue with liquibase adding interval to the current time as default value: <property name="expired" value="current_timestamp + interval '60 days'" dbms="postgresql"/> <addColumn tableName="user"> <column name="expired" type="timestamp" defaultValueDate="${expired}"> <constraints nullable="false"/> </column> </addColumn> Expired property always returns current date without adding 60 days. Is it possible? Or is there some mistakes in value field? Thank you in
