Re: BUG #13875: Error explaining query

HI Tom,

Sounds good.    I would like to help with the self-contained case.    What =
do you need from me?



Thank you,
Travis

What I get is

ERROR:  relation "IT_DIM_IRI_7472" does not exist LINE 4: "IT_DIM_IRI_7472"=
, "IRI_IT_M_2782_7472_O" WHERE
        ^

This does indeed sound like a bug, but without a self-contained test case, =
there's not a lot we can do about it.

            regards, tom lane
