Is it possible to design an arbitrary, hierarchical data scheme, that would allow its modification & extension during devel process?
In ideal case, it should also support some inheritance. I tried ltree for the hierarchy, and that worx fine. But I ran into problems when traversing across different tables connected by id. The DS and SELECTing just gets too complex to handle. And too inefficient, maybe. Does somebody have any experience with this? I'm thinking of it for too long now and i'm getting a little desperate.
Thank You, Petr.
