Inherits: "RecipeParameterSnapshot"
Are they *referenced* by other tables' foreign keys? But in any case,
the issue isn't about ALTER TABLE in itself, it's that some preceding
uncommitted operation had left some trigger events (read: FK
conditions that need to be verified). Doesn't matter which columns
those might be on.
Hmm, that makes more sense. None of these columns are referenced by
someone else, but it's possible that some foreign key is being
referenced or handled earlier in the transaction. I'll look in that
direction; thanks!
