MySQL Bugs: #63081: INSERT DELAYED fails for merge table for single record, ok for multiple records.

Bug #63081	INSERT DELAYED fails for merge table for single record, ok for multiple records.

Category:	MySQL Server: General	Severity:	S2 (Serious)
Version:	5.0.77	OS:	Linux (RedHat Enterprise)
Assigned to:		CPU Architecture:	Any
Tags:	DELAYED, insert, merge

Description:
When attempting to insert a single record into a merge table with the DELAYED option, the query failes with the error "ERROR 1031 (HY000): Table storage engine for 't' doesn't have this option"

However, and insert statement with the DELAYED option and multiple records completes normally.

How to repeat:
create table t1(x int);
create table t2(x int);

create table t(x int)ENGINE=MERGE UNION=(t1,t2) INSERT_METHOD=LAST;

This Works:
 insert delayed ignore into t values(1);
 
This fails with the error noted above:
 insert delayed ignore into t values(1),(2);

Suggested fix:
Make the behavior consistent between single record and multiple record insert queries.

Please, check with a newer version, 5.0.91+. For me everything is consistent:
