Hi,

I have a problem which I don't understand. I have and do:
instance a, libc based, PostgreSQL 15.10:
mydb=# \l mydb
List of databases
Name | Owner | Encoding | Collate | Ctype | ICU Locale | Locale
Provider | Access privileges
------+---------+----------+-------------+-------------+------------+-----------------+-------------------
mydb | my_user | UTF8 | en_US.UTF-8 | en_US.UTF-8 | | libc
|
$ pg_dump -Fc -Z1 -b mydb -f mydb.dump.gz
$ ls -l mydb.dump.gz
-rw------- 1 postgres postgres 14660308577 Feb 6 08:45 mydb.dump.gz
instance b, libicu based, PostgreSQL 17.2:
$ psql postgres
# create database mydb;
# \l mydb
List of databases
Name | Owner | Encoding | Locale Provider | Collate | Ctype |
Locale | ICU Rules | Access privileges
------+----------+----------+-----------------+-------------+-------------+--------+-----------+-------------------
mydb | postgres | UTF8 | icu | en_US.UTF-8 | en_US.UTF-8 |
en-US | |
$ pg_restore -cC --if-exists --disable-triggers -d mydb mydb.dump.gz
I would start by doing:
1) Log into postgres database and do:
a) DROP DATABASE mydb;
b) CREATE DATABASE mydb <options>;
2) pg_restore -d mydb mydb.dump.gz
pg_restore: error: could not execute query: ERROR: insert or update on table "table_1"
violates foreign key constraint "..._fk"
DETAIL: Key (dokument_id)=(1000033680) is not present in table "...".
Is dokument_id an integer field?
Command was: ALTER TABLE ONLY myschema.table
ADD CONSTRAINT table_fk FOREIGN KEY (dokument_id) REFERENCES
myschema.dokument(id);
pg_restore: error: could not execute query: ERROR: insert or update on table "table_2"
violates foreign key constraint "..._fk"
DETAIL: Key (dokument_id)=(1000033740) is not present in table "dokument".
Command was: ALTER TABLE ONLY vostra2_str.nen_dokument
ADD CONSTRAINT table_fk FOREIGN KEY (dokument_id) REFERENCES
myschema.dokument(id);
What am I doing wrong or how can I better achieve that? Any help would be
appreciated.
In a follow post you said:
"Everything works for all databases. Only this one has that problem."
Do you mean you made the same libc --> icu change on the other databases
with no errors?
Thanks in advance.
Paul
