Liquibase update error
I found the answer here: https://forum.liquibase.org/t/message-regarding-an-empty-result-set-for-databasechangeloglock/1487/2
Deleting the databasechangeloglock table solved it for me.
We have experienced a problem with the same core exception when trying to use liquibase using postgresql 10.4:
Caused by: liquibase.exception.DatabaseException: Expected single row from liquibase.statement.core.GetViewDefinitionStatement@1de5f25 but got 0`
It seemed that for us it was a problem with our jdbc driver.
The solution for us was to upgrade the jdbc driver from 9.3-1102-jdbc41 to 9.4-1202-jdbc41.
