Hi!
I have backed up a database with a 'UTC' timezone, but i can not to
restore it on a database with 'localtime' timezone.
Dealing with time is complex, so some inline questions below to try to
figure out exactly what the setup is.
I have a time constraints, the reason of the mistakes.
* First, I did: 'alter database set timezone='UTC'; ' but no
restore it...
On the database you took the backup from or the one you are restoring to?
* After I did change 'timezone' to UTC in postgresql.conf and
restart , but :(
From the source(backup) Postgres instance or the destination(restore)
instance?
* at last, i did 'pg_restore -l backup.dmp| sed "s:+00:-06:g"|psql
The above is not the complete command, correct?
What is the complete command?
database but copy fails with some records, so some tables are empty :(
* i will try replacing +00 by empty string, but ...
In psql and in the receiving database, what does:
show timezone;
return?
Are the timestamp fields you are COPYing into declared with timezone or
without timezone?
Why I can not restore it?
* I have using postgresql 9.4
* The backup is made it with pg_dump -Fc and
* I try to restore with pg_restore -d database --disable-triggers
* This is the message: COPY failed for table "stlm_201012ad": ERROR:
new row for relation "stlm_201012ad" violates check constraint
"time_stamp_201012ad"
DETAIL: Failing row contains (..., 2011-01-01 00:00:03.925+00, .., 0).
* this the constraint: "time_stamp_201012ad" CHECK (time_stamp >=
'2010-12-01'::date AND time_stamp < '2011-01-01'::date)
if change 2011-01-01 00:00:03.925+00 to 2011-01-01 00:00:03.925-06 works ok
