    it as '\\\\' (the backslashes are stripped once by the parser

  SYNOPSIS

  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
  sets the value of the bool pointer supports_delayed_inserts to 0 if not
  supported, 1 if it is supported.
