What is the maximum number of > table references possible? Why are you doing this? I can't imagine queries with that many table references ever being something useful? I'm pretty sure there's better solutions for what you're doing. > Can I increase this number somehow? It's not impossible, it's not entirely trivial either. The relevant variables currently are 16bit wide, and the limit is close to the max for that. Greetings, Andres Freund
