If this is a HEAP table, the automatic DELETE FROM which is written to the
binlog when a HEAP table is opened for the first time since startup, must
not be written: 1) it would be wrong (imagine we're in CREATE SELECT: we
don't want to delete from it) 2) it would be written before the CREATE
TABLE, which is a wrong order. So we keep binary logging disabled.
