org.hibernate.test.annotations.dataTypes.BasicOperationsTest fails on PostgreSQL Plus 13.1 with a ComparisonFailure

This is a clone of https://hibernate.atlassian.net/browse/HHH-14673

Running org.hibernate.test.annotations.dataTypes.BasicOperationsTest.testCreateAndDelete on PostgreSQL Plus 13.1 results in a ComparisonFailure:

org.junit.ComparisonFailure: ID expected:<[DATE]> but was:<[TIMESTAMP]>
    at org.junit.Assert.assertEquals(Assert.java:115)
    at org.hibernate.test.annotations.dataTypes.BasicOperationsTest$ValidateSomeEntityColumns.validateColumn(BasicOperationsTest.java:120)
    at org.hibernate.test.annotations.dataTypes.BasicOperationsTest$ValidateSomeEntityColumns.execute(BasicOperationsTest.java:97)

whilst on a PostgreSQL 13.2 this issue is not present (java.util.Date is correctly mapped as java.sql.Date). There could be some difference in database drivers or dialects - unfortunately, there is a lack of knowledge from my side in order to define the possible reason.

Environment:

oracle-java-1.8
postgresplus 13.1
hibernate.dialect org.hibernate.dialect.PostgresPlusDialect
EnterpriseDB JDBC Driver 42.2.12.3
