We are running RT 3.6 with a database with over 190 thousand tickets  
on PgSQL.
We added the following indexes to the databse:

CREATE INDEX groupstest1 ON Groups (lower(Domain));
CREATE INDEX groupstest2 ON Groups (lower(Type));
CREATE INDEX groupstest3 ON Groups  
(lower(Domain),Instance,lower(Type),id, Name);
CREATE INDEX groumemberstest1 ON groupmembers (groupid);
CREATE INDEX groumemberstest2 ON groupmembers (memberid);
CREATE INDEX userstest1 ON Users (lower(name));

PS: You should change the INDEX name, I just copied this from the test
