v0.18.0 insert all records:

dev=> SELECT COUNT(*) from usertable;
 count
-------
  1000
(1 row)

v0.19.0 only insert 4 records:

dev=> SELECT COUNT(*) from usertable;
 count
-------
  4
(1 row)

[huangjw806]

It seems that there is a conflict in the insert data on new version. It seems that only the number of records with the same threadcount data can be inserted.
