NOTES:
[16.06.2024] pzotov
Plan for FB 5.x and 6.x changed since 28-may-2024, build 6.0.0.363 #95442.
It was adjusted after talk with dimitr: must be the same for all FB versions
(with only difference: 'Sub-query' at the top line for FB 5.x+).
Changed filler character for show padding ('#' --> '.').
