Error while inserting UUID array with PostgreSQL

I have an attribute in one of my entity class as below



@Column(name = "idc_reviewer", columnDefinition="_uuid")

private UUID reviewer;


While saving the entity, I am getting below error.



ERROR: column "idc_reviewer" is of type uuid but expression is of type bytea

  Hint: You will need to rewrite or cast the expression.


I tried replacing columnDefinition with pg-uuid but that too didn't work.



Software Version:
Hibernate: 5.2.17
SpringBoot: 2.0.3






java postgresql hibernate spring-boot postgresql-10

  • How do you expect that postgres will store an array in a table column?

    @M.Deinum: because Postgres supports it (but apparently Hibernate does not)

  • Hmm... Learned something new :). You probably need a custom type for this then. And of course Vlad has you already covered (see vladmihalcea.com/…).
