I have following entity and some sample data is being loaded using liquibase loadData
@Entity
class MyEntity {
@Id
private Long id;
@Lob
@Column(name="my_text")
private String myText;
}
To load sample data using liquibase, following csv file has been used.
id;my_text
1;referenceToFile
And the content of referenceToFile
This is a very large text
The liquibase definition is as following:
<changeSet id="123455-1-data" author="user">
<loadData
file="config/liquibase/data/myentity.csv"
separator=";"
tableName="myentity">
<column name="id" type="numeric"/>
<column name="my_text" type="blob"/>
</loadData>
</changeSet>
However, when loading data using hibernate, I am getting following error.

Then I came across this site http://www.solewing.org/blog/2015/08/hibernate-postgresql-and-lob-string/ where it says postgres stores text somewhere else and keep a long reference. But liquibase seems inserting directly the text value rather than complying with postgres text type.
My question is how can we load the data correctly using liquibase for text type?
