Hello,
We have a development database that reports a larger size than the sum of it's relations and I was hoping someone had some insight into this issue. The consumed space is reflected in the size of the data directories PostgreSQL is maintaining on disk, so it's just not a reported size issue.
This is the version of Postgres we are using:
FVDM=# select version();
version
-----------------------------------------------------------------------------------------------------------
PostgreSQL 9.6.11 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23), 64-bit
pg_database_size reports this size:
name | owner | size
------------+----------+---------
FVDM | postgres | 43 GB
Running a query to report the total relation size of each schema results in this:
schemaname | pg_size_pretty
--------------------+----------------
information_schema | 152 kB
pg_catalog | 7880 kB
public | 52 MB
mart | 439 MB
(4 rows)
The total size of the relations is less than a gigabyte, but the database is 43GB in size. I've checked each table and there aren't any added indexes, so I'm very confused.
We've run vacuum full and reindex on the database with no reduction in size and a vacuum analyze verbose reports no recoverable rows. I cloned the machine for troubleshooting and even attempted truncating every table in the database to see if that remedied the issue. The only thing that has reclaimed the space is dropping the database and restoring from backup.
What is using the space and how do we reclaim it?
Any help or insight would be greatly appreciated, I'm at a loss as to what is consuming this space.
