It's extremely unlikely that this is a Postgres bug.
What is more likely is, that somewhere in your Java code the values get switched.
One way to find out, is to enable logging of all generated SQL statements
in your Java application. You mentioned JPA, so you are likely to use Hibernate.
This can e.g. be done using:
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
alternatively do it through the configuration of your logging framework.
You can also use "show_sql" in your persistence.xml if I'm not mistaken
(I don't know the details I keep away from obfuscation layers)
Another option is to turn on logging of all DML statements on the Postgres
side, using "log_statement=mod" in postgresql.conf
I am pretty sure with either one of those approaches you will see
that your application actively sends DML statements that change the data
in the database.
