Is it possible to use subqueries within alter expressions in PostgreSQL?
I want to alter a sequence value based on a primary key column value.
I tried using the following expression, but it wouldn’t execute.
alter sequence public.sequenceX restart with (select max(table_id)+1 from table)
I don’t believe you can do it like that but you should be able to use the setval function direction which is what the alter does.
The false will make it return the next sequence number as exactly what is given.
