Trouble with foreign key

Hi,

there is a problem with foreign key (PG 8.3RC2). Please, look at below. I don't understand this behavior. Why this
INSERTis ending with this error message. In my opinion, the key is obviously present. Thank you.

Before you go any further, I'd highly suggest updating.  8.3 was
released over 2 months ago, and has already progressed to 8.3.1.

Upgrade, check the release notes, then see what's up.

How is your foreign key defined?

 From a quick look it seems the column is named "_stamp" not
"_tmp_stamp" in the tmp_stamp table.
