Is there a way for dovecot to use a pool of sql (mysql) servers and load

Also fallback to next available sql server if connection to previous one

Can dovecot do such things currently? (If not this is feature request).

Yes, it can! Just add more multiple host= parameters to connect string. It's actually even documented in the dovecot-sql-example.conf:

#   MySQL supports multiple host parameters for load balancing / HA.

I guess it's not mentioned in the wiki though.
