Postgres SERIAL and BIGSERIAL are created as INT / BIGINT without auto increment

The following liquibase changeset does not work as expected

        <createTable tableName="test">
            <column name="id" type="SERIAL">
                <constraints nullable="false" primaryKey="true"/>
            </column>
        </createTable>

This changeset results in sql

CREATE TABLE test (id INTEGER NOT NULL, CONSTRAINT TEST_PKEY PRIMARY KEY (id));

In liquibase 3.6.3 and earlier the type SERIAL was used for the column which means that a sequence is automatically included.

This issue seems to be caused by #874 It appears that SERIAL columns are replaced by INT, however liquibase does reconize that this column type is an auto increment column.

It would be acceptible if the generated sql would be

CREATE TABLE test (id INTEGER GENERATED BY DEFAULT AS IDENTITY NOT NULL, CONSTRAINT TEST_PKEY PRIMARY KEY (id));

Is there any news on this?

I solved this problem for myself simply by explicitly adding autoIncrement

<column name="id" type="SERIAL" autoIncrement="true"/>
