Relax date format requierment (UTC)

[blogh]

Hi,

https://github.com/dalibo/pgtoolkit/blob/249034a214cddc223b7b7d4162f056ceb93899ca/pgtoolkit/log/parser.py#L128

Would it be possible to have an option to bypass this requirement ? I wanted to use this class to handle log parsing in a project where I just needed the date "as is" and couldn't because of this.

Looks reasonable. By the way, it's not clear to me why datetime.strptime() is not used directly here.

maybe it's because there are several formats in log_line_prefix ?

https://www.postgresql.org/docs/14/runtime-config-logging.html#GUC-LOG-LINE-PREFIX

  # %m (Time stamp with milliseconds)+ log_timezone = Europe/Paris
>>d = datetime.datetime.strptime("2021-09-22 19:00:45.894 CET", "%Y-%m-%d %H:%M:%S.%f %Z")

  # %t (Time stamp without milliseconds)
>>d = datetime.datetime.strptime("2021-12-07 10:14:04 CET", "%Y-%m-%d %H:%M:%S %Z")

--# %n (Time stamp with milliseconds (as a Unix epoch)) (not supported in pgtoolkit, never seen it, do we want it ?)
>>d = datetime.datetime.fromtimestamp(1638868691.099)

We could try different parsing methods (strptime, or even datetime.fromisoformat() when there is no tz info). Another option would be to use https://dateutil.readthedocs.io/en/stable/ but that would pull a dependency (the first, IIRC).

@blogh, if you need something to be changed in some way, feel free to submit a patch.
