Re: Newbie needs help with space issue - Mailing list pgsql-admin

this sql for table size ends with error that some of relation was not found.

So this is better one:

    select
        t.schemaname ,

t.tablename as object
,pg_size_pretty(pg_relation_size(schemaname || '.' || tablename))
,pg_size_pretty(pg_total_relation_size(schemaname || '.' || tablename))

    from
        pg_tables t
    where 1=1
        --and t.schemaname = 'public'
        --and t.schemaname <> 'public'
    order by  pg_total_relation_size(schemaname || '.' || tablename) desc;

Hi,

Also you might want to check the logging settings and log file sizes if logging is enabled. Sometimes due to some issues in database, the number of log file entries can be a lot leading to large log files.

Hi,

Here's a query to list individual table sizes:

    select
        t.tablename as "object",
        pg_size_pretty(pg_relation_size(cast(t.tablename as text))) as "data",
        pg_size_pretty(pg_total_relation_size(cast(t.tablename as text))) as "total"
    from
        pg_tables t
    where
        t.schemaname = 'public'
    order by
        pg_total_relation_size(cast(t.tablename as text)) desc

I think the last column includes index sizes.

Running this repeatedly over time should show what's growing.

cheers,
raf
