Using the Postgres demo database called dvdrental for experimentation purposes. I tried to generate a changelog and got the field "release_year" in table "film", which originally is an int, to be a "year(10)". I also had an issue with smallint(5), which another issue here in Jira already covers.
Note: wanted to say Version 3.8.5 in the field, but the newest Version in this Jira is 3.8.3
This only happens for this one field. Every other integer works fine.
Windows 10, psql 12.1, Liquibase 3.8.5
