**Describe the unexpected behaviour**
currently data format name started with `timestamp`(timestamp/timestamptz) all converted to DateTime in postgres engine, this will losing precision of millisecond and microsecond, so they should be regarded as DtateTime64 data format


**Expected behavior**

they should be regarded as DtateTime64 data format
