42.2.3 regression in fn timestampadd(SQL_TSI_MINUTE) - Mailing list pgsql-jdbc

Simple Java 8 test case below outputs different results when run against the 42.2.2 driver vs. the just released 42.2.3 driver:

PostgreSQL JDBC Driver 42.2.2
PostgreSQL 10.4 database "labkey2"
SQL_TSI_SECOND: 2003-01-01 00:00:03.0
SQL_TSI_MINUTE: 2003-01-01 00:03:00.0
SQL_TSI_HOUR: 2003-01-01 03:00:00.0

PostgreSQL JDBC Driver 42.2.3
PostgreSQL 10.4 database "labkey2"
SQL_TSI_SECOND: 2003-01-01 00:00:03.0
SQL_TSI_MINUTE: 2003-01-01 00:00:03.0
SQL_TSI_HOUR: 2003-01-01 03:00:00.0

SQL_TSI_MINUTE seems to be acting like SQL_TSI_SECOND in 42.2.3.
