Description

testSimpleEval("select '1980-04-01 01:50:01'::timestamp::bigint;", new String [] {"323369401000"});
    testSimpleEval("select ('1980-04-01 01:50:01'::timestamp)::bigint;", new String [] {"323369401000"});

The above unit tests can cause failure due to the precision difference between bigint value and the value casted from timestamp string. This patch eliminates the difference by using only timestamp strings.

testSimpleEval("select '1980-04-01 01:50:01'::timestamp::bigint::timestamp", new String [] {"1980-04-01 01:50:01"});
    testSimpleEval("select cast (('1980-04-01 01:50:01'::timestamp)::bigint as timestamp)",
        new String [] {"1980-04-01 01:50:01"});
