TITLE:       Verify ability to create database with different values of PAGE_SIZE
DESCRIPTION: Test creates database with specifying different values for page_size, each is degree of 2, from 0 to 256 Kb.
NOTES:
    This test replaces old ones: test_03, test_04, test_05, test_06, test_07 and test_12.
    Custome database config object is used here.
    Checked on 6.0.0.172, 5.0.0.1294, 4.0.5.3040, 3.0.12.33725
