I am trying to run my migration scripts on newest Liquibase, and encountered the issue. Minimal changeset to reproduce is:
When it is running on my PostgreSQL 9.2 error is printed:
The reason is that CREATE SEQUENCE IF NOT EXISTS construction is available in PostgreSQL only since 9.5.
Liquibase versions before 3.8.1 are running it as expected.
Liquibase 3.8.1 till 3.8.5
