Been doing some testing. Sequences are tied to schemas as far I can see.
I created a table in a non-default tablespace with a sequence. The table
got created in the tablespace, but the sequence remained in the default
tablespace.

So I am trying to figure out how your sequences in another tablespace?

If you do something like this:

postgres@test=# select * from pg_class where relname='t_id_seq';


what do you see for reltablespace ?
