I would like to know if plugins of sieve support UserDB/SQL backend. For example, for the vacation plugin, is it possible to retrieve a field like "sieve_vacation_days", "sieve_vacation_reason", and so on.. on user_query?

Not really, especially not in the Sieve standard. There is a experimental plugin for something like that. It can use Dovecot dictionaries to retrieve external data. It is documented here:
