   Thanks @tustvold 
   
   Should we support all supported PG formats 
https://www.postgresql.org/docs/current/datatype-datetime.html#DATATYPE-DATETIME-TIME-TABLE
   
   I'm doing some test 
   ```
           let valid = StringArray::from(vec![
               "2023-01-01 04:05:06.789000-08:00",
               "2023-01-01 04:05:06.789000-07:00",
               "2023-01-01 04:05:06.789 PST",
               "2023-01-01 04:05:06.789-8",
               "2023-01-01 04:05:06.789-800",
               "2023-01-01 04:05:06.789-8:00",
               "2023-01-01 04:05:06.789+07:30:00",
               "2023-01-01 040506+07:30:00",
               "2023-01-01 040506+0730",
               "2023-01-01 040506 America/Los_Angeles",
               "2023-01-01 04:05:06",
               "2023-01-01",
   
           ]);
   ```
   All those valid for PG, but there is potential performance problem as we 
need to iterate through multiple formats until we find the match
