my table is empty, pg_relation_size(name) return 38 MB

Hi Team,

Though my table is empty, pg_relation_size(name) return 38 MB. I use below
query to determine tables disk usages.

SELECT nspname || '.' || relname AS "Table",
pg_total_relation_size(C.oid) "Size",
pg_size_pretty(pg_total_relation_size(C.oid)) AS "Total size"
FROM pg_class C
LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)
WHERE nspname NOT IN ('pg_catalog', 'information_schema')
AND C.relkind <> 'i'
AND nspname !~ '^pg_toast'

Please help,
Thanks!
Shiva
