I found same kind of issue in postgresql also. I am also getting Error executing SQL SELECT COUNT(\*) FROM DATABASECHANGELOG: ORA-00942: table or view does not exist. this cause null pointer issue at public boolean isInheritableIgnore() {  
DatabaseChangeLog changeLog = this.getChangeLog();  
return changeLog.isIncludeIgnore(); // HERE  
}

Here’s what I am going to do, let me know @ned (or @smstromb) if you don’t have the same setup: install Liquibase (my local system is a Mac, what are you using?) Create a liquibase project (folder with liquibase.properties, changelog.xml) make sure liquibase.properties is pointing to a postgres db (what version are you using?) run a liquibase update and see if I get the databasechangeloglock table error. Thanks, Ronak
