Liquibase databasechangelog xml file - how to create enum in postgresql - postgresql

Question

I use liquibase and I want to create enum in my xml file (PostgreSQL).
As an example below changelog file (only a piece of the file) that creates new table:
<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog
xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-2.0.xsd
http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">
<changeSet id="r3.3.0_table_creation_research_document "
author="anonim">
<createTable tableName="research_document">
<column name="id" type="bigint">
<constraints primaryKey="true"
primaryKeyName="research_document_pkey" nullable="false" />
</column>
I can't find any info/examples in Internet!

I don't think liquibase supports enum for postgres natively in the xml format. However, since it is possible in postgres, you could always use liquibase's formatted sql instead of xml:
--liquibase formatted sql
--changeset ronak:1
CREATE TYPE mood AS ENUM ('sad', 'ok', 'happy');
CREATE TABLE person (
name text,
current_mood mood
);
--rollback drop table person;
