Hi, Please find the patch with issues fixed:
1) No handling for INTERVAL type datetime. For example: executing query *SELECT INTERVAL '15 minutes';* throws json serialization error, because it returns time in timedelta format which is not handled. Added support to handle *timedelta* datetime format in *DataTypeJSONEncoder* class 2) When we try to get BC dates from database raises ValueError: year is out of range For eg: *SELECT TIMESTAMP '0044-03-15 10:00:00 BC',* It is because pyscopg2 doesn't handle BC datetime format. So we have defined our method which type cast the datetime value to string in pyscopg2 overriding default behaviour. *Reference:* http://initd.org/psycopg/docs/advanced.html#type-casting-from-sql-to-python https://github.com/dbcli/pgcli/blob/ccf3693be62dd8a79ced19ed9d69f0708d2b3d6f/pgcli/pgexecute.py *Issue left:* Pyscopg2 not handling representation of BC dates. It is currently representing time in following query *SELECT TIMESTAMPTZ '2016-03-15 10:00:00+02 AD';* as 2016-03-15T00:00:00Z which is wrong. I will send patch for it when gets fixed. Please review. Thanks, Surinder Kumar
