Question

I recently switched from MySQL to PostgreSQL in my Django app and I need to set last values of all sequences on max. number of corresponding table and column. How can I get all sequences related to a table? So far I am doing somethign like:

SELECT sequence_name FROM information_schema.sequences 
WHERE sequence_name LIKE 'table_name%';

but I dont’t like this approach, mostly because I have to additionally clean the results. Is there some ID that connects table with their sequences.

Now I can’t add any object to my database, because Postgre “auto increment” is running from 1 and new objects’ PKs are clashing with existing records.

Note: My django app is quite large and I am using several additional package, so the naming convention is not consistent (table names are with / without app pefix, PK columns are like ‘tableid’ or ‘table_id’ of just ‘id’ and so on)

Answer 1

try with:

python manage.py sqlsequencereset <appname>

and feed that to psql cli
