Subject: size of attributes table is too big

Hello!

I have a PG (v16) instance which is occupying around 1TB of storage. Out of
this, around 350GB is occupied by the table pg_catalog.pg_attribute.
Why is the catalog table's size so big?

Here are the sizes:

pg_attribute
338 GB
pg_attribute_relid_attnam_index
117 GB
pg_attribute_relid_attnum_index
69 GB

I think this table must have tons of dead tuples. Please suggest to me if
we can purge any data/shrink the size of this table.
