Liquibase chooses wrong Database implementation in version 4.7.0

Environment

Liquibase Version: 4.7.0

Liquibase Integration & Version: CLI

Liquibase Extension(s) & Version: -

Database Vendor & Version: Azure SQL Database v12.0.2000.8

Operating System Type & Version: Ubuntu 18.04

Description

We recently started using Liquibase using the Docker image, we used the latest tag which resolved to Liquibase v4.7.0. We run the Liquibase container against multiple environments (Dev/Prod/etc) and some environments would consistently fail while others consistently succeeded. The commands were similar because we use a template, with only configuration (ip, username’s) differing according to the environment.

It would fail with the error message saying: Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Invalid column name 'FALSE'.

Even though the correct driver is being used (as shown in the logs below), Liquibase seems to be using PostgreSQL syntax. If googling for “pg_settings” it seems to be a PostgreSQL thing. Also, FALSE/TRUE seem to be PostgreSQL reserved keywords, that’s why Liquibase is trying to use FALSE/TRUE without quotations, this doesn’t work in MSSQL.

Steps To Reproduce

Run the Liquibase update command using version 4.7.0. We didn’t figure out why it would succeed on some environments and fail on others.

Actual Behavior

Liquibase would fail even before applying our changesets, these errors would only be visible after using --log-level=INFO: Log of Liquibase failing to find “pg_settings”:

Expected/Desired Behavior

As said before, some environments would succeed. Liquibase correctly executed the changesets. This is the kind of logging we would have expected on the failing environments:

Additional Context

We solved this issue by using Liquibase version v4.6.2 for now, this version gives us no problems and all of our changesets are executed succesfully. We changed the docker latest tag to 4.6.2.

@M-Koers release v.4.7.1 is out now and the fix to this is included. Thanks!
