row description for domain in 7.4

I created a domain with text as the data_type. When I get the row 
description message from the backend for a column using this domain, 
the type OID provided is for text (25) rather than the OID of the 
domain I created. I could have sworn I tested this in 7.3.x and the OID 
was for my domain. 7.4 bug or something I need to work out on my own?

Thanks,
