These management commands fail:
{{{
./manage.py sqlsequencereset | ./manage.py dbshell
}}}
Generated SQL from sqlsequencereset (Partial4x4 is from my application):
{{{
BEGIN;
SELECT setval(pg_get_serial_sequence('"Partial4x4_partial4x4"','id'),
coalesce(max("id"), 1), max("id") IS NOT null) FROM
"Partial4x4_partial4x4";
COMMIT;
}}}
Example of error:
{{{
BEGIN
ERROR: relation "Partial4x4_partial4x4" does not exist
LINE 1: ...alesce(max("id"), 1), max("id") IS NOT null) FROM "Partial4x...
^
ROLLBACK
}}}
PostgreSQL 15 blocks use of the public schema. This requires use of
database connection options to set the search path.
settings:
{{{
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'OPTIONS': {'options': '-c search_path=your_db_schema'}, #
critical
'NAME': 'your_db_name',
'USER': 'your_db_user',
'PASSWORD': 'your_db_password',
'HOST': 'localhost',
'PORT': '5432'
}
}
}}}
The SQL generated by sqlsequencereset fails because of not inserting a
command to set the search path.
Corrected SQL:
{{{
set search_path="your_db_schema";
BEGIN;
SELECT setval(pg_get_serial_sequence('"Partial4x4_partial4x4"','id'),
coalesce(max("id"), 1), max("id") IS NOT null) FROM
"Partial4x4_partial4x4";
COMMIT;
}}}
Containment that works for me:
{{{
(echo 'set search_path="your_db_schema";'; /manage.py sqlsequencereset
Partial4x4) | ./manage.py dbshell
}}}
