after index type got changed then daemon crashed after that point on daemon restart all transaction stored at binlog to that index got replayed and that index got content that is not intended for it.

Unless you're already working on this more details are required (crashlog etc.) to not forget what it's related with in future.

this is related to #764 the reproduction is:

• start daemon with idx1 type = repcolate and binlog enabled
• INSERT into idx1 VALUES ('query 1')
• change config for idx1 type = rt path = data/other_path
• send SIGHUP to daemon to reload config and recreate idx1 as RT instead of PQ index
• SELECT * FROM idx1 show that fresh index is empty RT index
• make daemon to crash
• daemon got restarted and repalys binlog
• SELECT * FROM idx1 show that is RT index has applied transactions from binlog stored there for PQ index, ie

that is wrong however as initial issue #764 said change of index type RT to PQ back and forth should be prohibited.
