Some mistakes, revealed by regression tests, passed at Raspberry PI4:
1. Fix uint64 format in some output messages.2. Input parameters conversion mistake in aqo_queries_update.3. Unneeded routine 'get_aqo_schema'.4. Fix type of the first parameter (counter) in aqo_cardinality_error() and aqo_execution_time() routines.5. Fix aqo_data() routine.
