Check if we the table is one of the table types that should be ignored:

MRG_ISAM, MRG_MYISAM, if opt_delayed, if that table supports delayed inserts.

If the table should be altogether ignored, it returns a true, false if it

should not be ignored. If the user has selected to use INSERT DELAYED, it
3049
sets the value of the bool pointer supports_delayed_inserts to 0 if not

supported, 1 if it is supported.
