Why is a String field with @Lob annotation stored as a number?

Question

Java

Hello )
The problem is that when saving an entity with a field

@Lob
@Column(name = "content")
private String content;

the entity is stored in the database as a number (it is not clear where it comes from), and it increases by one with each new saved entity, as if it were an ID. There is only one context, saving by the regular method through the CrudRepository. Column type in the database - TEXT.
The only thing is that the setter is built like a builder

public MyEntity setContent(String content) {
   this.content = content;
   return this;
}

Could this be the reason for this behaviour?
If you remove the @Lob annotation, then everything works fine. I'm kind of stuck.

There are two types of LOBs in PostgreSQL - BLOB and CLOB . Judging by the fact that the entity field is of type String, you need the second one. And this needs to be added:

@Lob @Type(type = "org.hibernate.type.TextType")
private String content;
