conditional rules VS 1 unconditional rule with multiple commands?
I just wonder whether the two are equivalent from user perspective: As far
as I see, you can always rewrite a multi-command rule as a conditional rule
and vice versa. Further more, Postgres seems to execute all the conditional
rules, just as if it would execute all the commands in the one unconditional
rule. So, I just wonder if there is any use in using conditionals in rules
over one multi-command rule?

I think if you want any meaningful answers you should start by explaining what exactly you mean by <subject>. An example would help.
