OK, This problem has been solved with below steps: (I'm using cmd)
Dump newsfeed.db to sql file:
Code:
sqlite3 newsfeed.db .dump > newsfeed.sql
Dump newsfeed.sql to new database
Code:
sqlite3 newsfeed.db < newsfeed.sql
It's very simple then compact my old file from 394MB to 57MB then clean up all my entries
