Guten Tag Tom Lane, am Samstag, 29. August 2020 um 17:19 schrieben Sie: > TBH, this seems like a pretty awful data design.

So if at all, oms_rec needs to be embedded into clt_rec entirely. While I considered that in the past already, wasn't sure if that is the best approach to model those two different data types. I'll make a note and consider refactoring at some point, so thanks for your opinion!
