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.
