Hi.
Thanks for config, but is there a possibility to avoid DRBD usage for postgres? 
DB on top of DRBD may be broken if master fails at DB write (because write 
isn't atomic process).

yes, there is a way: replication. You can use replication for Postgres (and 
mySQL too) with the newer RA:

Master becomes, who the newest data has.
