PS1, Line 688: 
Can you talk about why you removed unique_database? When I look at 
QueryTest/hdfs-text-scan-with-header I see DDL statements which could cause 
collisions.

There are 4 versions of this test in exhaustive:

<Module 'tests/query_test/test_scanners.py'>
  <Class 'TestTextScanRangeLengths'>
    <Instance '()'>
      <Function "test_text_scanner_with_header[exec_option: {'disable_codegen': 
True, 'abort_on_error': 1, 'exec_single_node_rows_threshold': 0, 'batch_size': 
0, 'num_nodes': 0} | table_format: text/none]">
      <Function "test_text_scanner_with_header[exec_option: {'disable_codegen': 
False, 'abort_on_error': 1, 'exec_single_node_rows_threshold': 0, 'batch_size': 
0, 'num_nodes': 0} | table_format: text/none]">
