Reading your reply to Andres-san, I feel sympathy about your attitude. Maybe we should outline the (rough) design
first,discuss/guess its complexity, and ask for opinions on whether it's worth expending our effort for the complexity
orchoose an easier hack, considering the assumed use case and ensuring future extensibility not to prevent smooth
enhancements.
With that said, I think the easy hack this time is good, because parallel INSERT/UPDATE/DELETE will only be used
infrequently(compared to short OLTP transactions) for data migration and batch processing where the source data is
ample. I don't think of a use case yet where we want to make parallel workers allocate an XID when only necessary.

Thank you for telling me the impression of the word. TBH, I knew the word for the first time, and looked it up in
English-Japanesedictionary. It didn't give good impression, and grotty sounds somewhat similar to grotesque, so I got
worried"Robert-san may be angry."
