Hi gurus,
i have two questions for you.
1) I would like to know if the system catalogs tables are created
for each database of Postgresql instance or belong to a specific db,
such as template0 i suppose.
2) As i had a very large pg_largeogject, i deleted rows e now i have a
clean, small table.
The table is empty but its index pg_largeogject_loid_pn_index lasts
to retain a lot of bytes.
How can i do?
I have to drop and recreate the index?
Thank you very much.
