make check failures in current cvs

While adding some test methods to test the COPY protocol, I've notice some
failures in the current cvs. Is this to be expected? Or does this point to
a problem with my local setup?

test:
    [junit] .................F......F................F..
    [junit] ...............
    [junit] Time: 12.438
    [junit] There were 3 failures:
    [junit] 1) testCapabilities(org.postgresql.test.jdbc2.DatabaseMetaDataTest)junit.framework.AssertionFailedError
    [junit]     at org.postgresql.test.jdbc2.DatabaseMetaDataTest.testCapabilities(DatabaseMetaDataTest.java:104)
    [junit] 2) testForeignKeys(org.postgresql.test.jdbc2.DatabaseMetaDataTest)junit.framework.AssertionFailedError
    [junit]     at org.postgresql.test.jdbc2.DatabaseMetaDataTest.testForeignKeys(DatabaseMetaDataTest.java:265)
    [junit] 3) testSetTimestamp(org.postgresql.test.jdbc2.TimestampTest)junit.framework.AssertionFailedError
    [junit]     at org.postgresql.test.jdbc2.TimestampTest.timestampTest(TimestampTest.java:120)
    [junit]     at org.postgresql.test.jdbc2.TimestampTest.testSetTimestamp(TimestampTest.java:92)

    [junit] FAILURES!!!
    [junit] Tests run: 56,  Failures: 3,  Errors: 0



Thanks,
