Create another database from changelog: automatic data type conversion issue

1. liquibase \
2.    --driver=org.postgresql.Driver \
3.    --classpath="C:\db_drivers\postgresql-9.3-1102.jdbc3.jar" \
4.    --changeLogFile="./postgresql_changelog.xml" \
5.    --url="jdbc:postgresql://localhost:5432/postgres" \
6.    --username=schema_name_here \
7.    --password=************** \
8.    --logLevel=debug \
9.    --defaultSchemaName=sep \
10.    generateChangeLog

Here is a fragment of postgresql_changelog.xml:

1. ...
   <createTable tableName="table1">
       <column name="total_pk" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="form_fk" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="territory_fk" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="parameter_fk" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="enterprise_fk" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="total_g" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="total_data" type="date">
           <constraints nullable="false"/>
       </column>
       <column name="total_value" type="numeric(*, 2)">
           <constraints nullable="false"/>
       </column>
       <column name="variant_fk" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="period_id" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="total_q" type="INT8"/>
       <column name="total_m" type="INT8"/>
       <column name="increase" type="INT8"/>
       <column name="period_index" type="INT8"/>
       <column name="data_input" type="TIMESTAMP WITHOUT TIME ZONE"/>
       <column name="document_unid" type="VARCHAR(64)"/>
       <column name="value_comment" type="VARCHAR(512)"/>
       <column name="olap_year" type="SMALLINT"/>
       <column name="olap_month" type="SMALLINT"/>
       <column name="olap_week" type="SMALLINT"/>
       <column name="olap_day_of_month" type="SMALLINT"/>
       <column name="olap_quarter" type="VARCHAR(4)"/>
       <column name="olap_quarter_desc" type="VARCHAR(17)"/>
       <column name="olap_month_name" type="VARCHAR(8)"/>
       <column name="ediz_id" type="INT8">
           <constraints nullable="false"/>
       </column>
       <column name="olap_month_code" type="VARCHAR(10)"/>
       <column name="olap_month_caption" type="VARCHAR(64)"/>
   </createTable>
   ...
   

Now I want to create the same objects and the same relationships in another database (Oracle):

1. liquibase
      --driver=oracle.jdbc.OracleDriver
      --classpath="C:\db_drivers\ojdbc14.jar"
      --changeLogFile="./postgresql_changelog.xml"
      --url="jdbc:oracle:thin:@ip_here:orabeta"
      --username=***
      --password=***
      update

But it does not work: ORA-00902

It is possible to get changelog from one database and update another database in different RDBMS server from this changelog? I need to get automatic data type conversion.
