MDEV-31361 Wrong result on 2nd execution of PS for query with derived table
This bug led to wrong result sets returned by the second execution of
prepared statements from selects using mergeable derived tables pushed
into external engine. Such derived tables are always materialized. The
decision that they have to be materialized is taken late in the function
mysql_derived_optimized(). For regular derived tables this decision is
usually taken at the prepare phase. However in some cases for some derived
tables this decision is made in mysql_derived_optimized() too. It can be
seen in the code of mysql_derived_fill() that for such a derived table it's
critical to change its translation table to tune it to the fields of the
temporary table used for materialization of the derived table and this
must be done after each refill of the derived table. The same actions are
needed for derived tables pushed into external engines.

MDEV-33251 Redundant check on prebuilt::n_rows_fetched overflow
row_search_mvcc(): Revise an overflow check, disabling it on 64-bit
systems. The maximum number of consecutive record reads in a key range
scan should be limited by the maximum number of records per page
(less than 2^13) and the maximum number of pages per tablespace (2^32)
to less than 2^45. On 32-bit systems we can simplify the overflow check.
MDEV-21472: ALTER TABLE ... ANALYZE PARTITION ... with EITS reads and locks all rows
This was fixed in 10.2 in 2020 but merging the code to 10.3 caused the
bug to come back.
