Digging a little more, I found that not only sequences were not moved but
also many tables in pg_catalog are still in my old tablespace. This is
expected since the query in the SQL files I used to move the tables and
indexes had a WHERE clause like this:
SELECT ' ALTER TABLE ' || schemaname || '.' || tablename || ' SET
TABLESPACE pg_default;'
FROM pg_tables
WHERE schemaname NOT IN ('pg_catalog', 'information_schema');
So I tried removing the WHERE clause and running the script again:
psql -U postgres -d mydb < move_tables_to_pg_default.sql | findstr /R
/C:"[ALTER]" | psql -d mydb -U postgres
I got many errors like this one:
ERROR: permission denied: "pg_event_trigger" is a system catalog
If I can't move tables from pg_catalog, how will I be able to drop that
tablespace I don't want to use anymore?
I am thinking that maybe using "ALTER DATABASE mydb SET TABLESPACE
pg_default;" instead would take care of all this, no?
But when I tried it last week, I got a message like: some relations already
in target tablespace...
Any help will be much appreciated.
