Liquibase produces wrong sql for column type of "BIGINT GENERATED BY DEFAULT AS IDENTITY"

Description

Hi there.
I tried to upgrade liquibase from 3.6.3 to 3.7.0 but faced with following issue.
Part of table definition:
<createTable tableName="my_table">
<column name="my_table_id" type="BIGINT GENERATED BY DEFAULT AS IDENTITY">
<constraints primaryKey="true" primaryKeyName="pk_my_table_id"/>
</column>
</createTable>

3.7.0 produces invalid sql
CREATE TABLE my_table(my_table_id BIGINT generated by default as NOT NULL

but 3.6.3 creates correct statement
CREATE TABLE my_table(my_table_id BIGSERIAL NOT NULL

Is there any workarounds?
