Here is a sandbox example of what I mean.
CREATE TABLE test_0

string_value varchar(2047),
timestamp_value timestamp with time zone

insert into test_0
(string_value)
values
('2010-03-12 17:06:21-0800'),
('2009-08-14 16:47:40+0500'),
('2010-03-22 22:45:59-0400');
As expected, select * from test_0; , produces the following:
string_value timestamp_value
2010-03-12 17:06:21-0800 <null>
2009-08-14 16:47:40+0500 <null>
2010-03-22 22:45:59-0400 <null>
I would like to parse the strings into their equivalent timestamps
and put them in the timestamp_value column.
My attempt, so far, to update the table:
update value
set
timestamp_value =
to_timestamp(string_value, 'YYYY-MM-DD HH24:MI:SS-XXXX');
Forget to_timestamp; just cast the string to timestamptz. The
regular timestamp input converter will handle that format fine.

That worked great.
Thanks very much,
