It gets stranger. I try this:
select
tablename
, pg_relation_size(tablename)
, pg_size_pretty(pg_relation_size(tablename) ) as relsize
, pg_size_pretty(pg_total_relation_size(tablename) ) as disksize
, pg_total_relation_size(tablename)
from pg_tables where schemaname <> 'information_schema'
order by 2 desc
And all the tables report a 'disksize' larger than the 'relsize', which seems natural. The biggest table (relsize) is around 5 GB.
I wonder where the rest of the size comes from?
