The phenomenon you are seeing occurs when there is a table with a
great deal of data.
Look for the table via the query:
select * from pg_class where oid = 69233123;
Presumably these files are for a table that contains multiple GB of
data. Or they could be for an index on a very large table.
If the data in the table/index is useless to you, you might consider
dropping the table/index.
