On http://liquibase.org/databases, the instructions for manually creating the Liquibase tables are incomplete. Besides creating DatabaseChangeLog as shown there, one must also do the following:
CREATE TABLE DatabaseChangeLogLock (
ID INT NOT NULL,
LOCKED BOOLEAN NOT NULL,
CONSTRAINT PK_DATABASECHANGELOGLOCK PRIMARY KEY (ID)
INSERT INTO databasechangeloglock (ID, LOCKED) VALUES (1, FALSE);
This could usefully be added to the page in question. Is this the best place to suggest such changes, or is it better to file a JIRA issue?
