Problems with Diff functionality on PostgreSQL

[MaslovD]

Once I create initial Diff change log, every following run of mvn clean install liquibase:diffgenerates a number of useless changeLog records.

For example, after initial run of mvn clean install liquibase:diff we the following file (which looks almost correct): `databaseChangeLog:

• changeSet: id: 1578360036411-1 author: your_liquibase_username (generated) changes:
  • createTable: columns:
  • column: autoIncrement: true constraints: primaryKey: true primaryKeyName: rolesPK name: id type: BIGINT

after following run of mvn clean install liquibase:diff, I have new list of changes:

We have the same problem with 3.8 version, in previous versions this problem also occurs, but with a bit different changesets structure.

[aneri90]

Still happening in version 4.1.1

[MaslovD]

Finally stopped wasting time, switched back to FlyWay.

It seems to be caused by https://github.com/liquibase/liquibase/issues/2069
