\COPY table1 FROM '/tmp/Oracle_2020_06.csv' DELIMITER ',' CSV HEADER;
ERROR:  invalid input syntax for type timestamp: "01-JUN-20 06.04.20.634000 AM"
CONTEXT:  COPY table1, line 2, column last_update_timestamp: "01-JUN-20 06.04.20.634000 AM"

Appreciate any help with this psql command.

The table column definition:

          Column           |              Type              |
---------------------------+--------------------------------+
 last_update_timestamp     | timestamp(6) without time zone |

Thanks & Regards

I would recommend issuing one of these on the Oracle side *before* taking the CSV snapshot.
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
ALTER SESSION SET nls_date_format='YYYY-MM-DD HH24:MI:SS';

Otherwise, you have to load this CSV file in a table, that has `text` type for the column and do a post-processing,
smth like:

    INSERT INTO permanent_tab
    SELECT *, to_timestamp(col, 'DD-MON-YY HH12.MI.SS.SSSSS AM') FROM temp_table;

Hope this helps.

The problem is psql doesn't understand/recognise the timestamp format
being used in the CSV dump from Oracle.

Modify the SQL used to extract the data from Oracle so that it formats
the timestamp as a string which psql can parse into a timestamp type -
for example ISO or any of the psql timestamp formats (see psql manual).
