Dear Friends,
I am newbie to postgresql.
I have 162 GB on my database but when I check size of all tables, I approximately obtain 80 GB.
I also see that I have 68GB of temporary files however I only found 2.4MB at postgres/data/base/pgsql_tmp.
Exactly how did you determine this?
Could you tell me what are those temporary files and where are they at? Can I delete some of them?
All values come from pgAdmin 4 and checked by my own SQL queries(postgresql-9.6).
Can you show actual queries used?
I already run vacuum full and there is few dead tuples.
Best regards,
Jimmy AUGUSTINE

I am not sure what your query was that deteremined table and index sizes, but try using the query instead.
Note that total_size is the size of the table and all it's indexes.
SELECT n.nspname as schema,
c.relname as table,
a.rolname as owner,
c.relfilenode as filename,
c.reltuples::bigint,
pg_size_pretty(pg_relation_size(quote_ident(n.nspname) || '.' || quote_ident(c.relname) )) as size,
pg_size_pretty(pg_total_relation_size(quote_ident(n.nspname) || '.' || quote_ident(c.relname) )) as total_size,
pg_relation_size(quote_ident(n.nspname) || '.' || quote_ident(c.relname) ) as size_bytes,
pg_total_relation_size(quote_ident(n.nspname) || '.' || quote_ident(c.relname) ) as total_size_bytes,
CASE WHEN c.reltablespace = 0
THEN 'pg_default'
ELSE (SELECT t.spcname
FROM pg_tablespace t WHERE (t.oid = c.reltablespace) )
END as tablespace
FROM pg_class c
JOIN pg_namespace n ON (n.oid = c.relnamespace)
JOIN pg_authid a ON ( a.oid = c.relowner )
WHERE quote_ident(nspname) NOT LIKE 'pg_%'
AND quote_ident(relname) NOT LIKE 'pg_%'
AND quote_ident(relname) NOT LIKE 'information%'
AND quote_ident(relname) NOT LIKE 'sql_%'
AND quote_ident(relkind) IN ('r')
ORDER BY total_size_bytes DESC, 1, 2;
