I would like to announce a new extension called Liquibase Spatial. It adds the ability to handle spatial indexes and geometry types in Derby, H2, MySQL, PostgreSQL and Oracle.
A brief overview is available on the extensions portal: https://liquibase.jira.com/wiki/display/CONTRIB/Spatial+Extension
The project page is on GitHub: https://github.com/lonnyj/liquibase-spatial
I’ve been using it at work and it has functioned well for me and helped me eliminate some database-specific configuration. Hopefully someone will find it handy for them as well.
