table stems from the fact that such drop does not commit an ongoing
transaction and changes to non-transactional tables must be written
ahead of the transaction in some circumstances.
6- Slave SQL thread ignores all replicate-* filter rules
for temporary tables with 'IF EXISTS' clause. (See sql/sql_parse.cc:
mysql_execute_command() for details). These commands will be binlogged
as they are, even if the default database (from USE `db`) is not present
on the Slave. This can cause point in time recovery failures later
when user uses the slave's binlog to re-apply. Hence at the time of binary
logging, these commands will be written with fully qualified table names
and use `db` will be suppressed.
