Hi,
my standard query (adapted to 1mb size) is:
select
t.spcname as "tablespace"
, pg_get_userbyid(c.relowner) as "owner"
, n.nspname as "schema"
, relname::text as "name"
, pg_size_pretty(pg_total_relation_size(c.oid))::text as "total size"
, case
when c.relkind='i' then 'index'
when c.relkind='t' then 'toast'
when c.relkind='r' then 'table'
when c.relkind='v' then 'view'
when c.relkind='c' then 'composite type'
when c.relkind='S' then 'sequence'
else c.relkind::text
end as "type"
from
pg_class c
left join pg_namespace n on n.oid = c.relnamespace
left join pg_tablespace t on t.oid = c.reltablespace
where
(pg_total_relation_size(c.oid)>>20)>0 and c.relkind!='t'
order by
c.relkind desc, pg_total_relation_size(c.oid) desc
Andrus schrieb:
SELECT oid, relname::char(35) as Table_Name,
pg_size_pretty(pg_total_relation_size(oid))::VARCHAR(15) as
Total_Table_Size
FROM pg_class
where pg_total_relation_size(oid)/(1024*1024)>0
ORDER BY pg_total_relation_size(oid) desc
returns table names with size greater than 1 MB
How to modify this so that schema name is also returned?
I have lot of tables with same name and thus this output is difficult
to understand.
pg_class seems not contain schema names.
Andrus.
