[PATCH] Fix duplicate errmsg in ALTER TABLE SPLIT PARTITION

Mon, 20 Apr 2026 21:34:42 -0700 

Hi hackers,

The ereport() in transformPartitionCmdForSplit() that fires when
splitting a non-default partition while a default partition already
exists has two errmsg() calls:

    ereport(ERROR,
            errcode(ERRCODE_INVALID_OBJECT_DEFINITION),
            errmsg("can not split non-DEFAULT partition \"%s\"", ...),
            errmsg("new partition cannot be DEFAULT because ..."),
            parser_errposition(...));

The second one should had been errdetail()

The attached patch changes the second errmsg() to errdetail().

Also, I think "can not" can be replaced with "cannot" for consistency
throughout? Havent added is as part of this patch though. Thoughts?

Regards,
Ayush
