Hi! I am a PhD student, researching on using databases to implement network control infrastructure. For this purpose, I wanted to use conditional tables <http://users.encs.concordia.ca/~grahne/papers/conditional.pdf> in databases, which allow representing unknown values in a DB with conditions over tuples. However, I could not find any DBMS that supports them. Are there any postgres extensions/features that implement conditional tables? I wanted to confirm by asking here in case I missed something in my search.
Thanks in advance! Best, Mubashir
