1) display warnings when DB is close to xidWrapLimit by 200M transactions
2) remove '\r' symbol from queries for better display at email clients
fix incorrect numbering of queries when there is no 'other' query, fix IO percentage at total time when there is very little / no activity on database since last pg_stat_statements reset.
1) display track utilities information
2) display most returning rows queries with % of total rows
3) speed up execution in case of very long queries
4) truncate query to 8kb size in report
fix possible incorrect filtration of top I/O queries.
