One option:

1) Import into staging table as varchar field.

2) Use to_timestamp()(NOTE change in template pattern) from here:

https://www.postgresql.org/docs/current/functions-formatting.html

select to_timestamp('2013061914122501', 'YYYYMMDDHH24miSSCC');
to_timestamp

to move the data into final table.
