Thread: command to check the database size ?
Hi
Please help, I am new to postgres administration. I just need a command to check the size of the database.
I tried searching but no luck. The server is running on Postgres 7.3.4 and O/S Linux Centos 5. The data sits on /data/postgres7.3.4/data directory. There is no directory like /usr/src/postgresql-7.3.4/contrib/dbsize
But the backup server which is also running postgres 7.3.4 but on Redhat 9 does have /usr/src/postgresql-7.3.4/contrib/dbsize directory which has the following files but I don’t what to from from:
[root@c9903 dbsize]# pwd
/usr/src/postgresql-7.3.4/contrib/dbsize
[root@c9903 dbsize]# ls -ltrh
total 16K
-rw-r--r-- 1 70 wheel 201 Feb 23 2002 Makefile
-rw-r--r-- 1 70 wheel 253 Apr 2 2002 dbsize.sql.in
-rw-r--r-- 1 70 wheel 554 Jun 23 2002 README.dbsize
-rw-r--r-- 1 70 wheel 2.6K Sep 4 2002 dbsize.c
[root@c9903 dbsize]#
I also could not find functions like pg_database_size(), pg_size_pretty()
,etc in this old version of postgres7.3.4.
In summary I can’t find the command to find the database size from the main server and from the backup server.
Please help
Thanks

Execute this against the database that you want to check the size of:
SELECT schemaname, tablename,
pg_size_pretty(size) AS size_pretty,
pg_size_pretty(total_size) AS total_size_pretty
FROM (SELECT *,

pg_total_relation_size(schemaname||'.'||tablename) AS total_size
FROM pg_tables) AS TABLES
WHERE schemaname='public'
ORDER BY total_size DESC;
This will get it by table ….

Thanks Plugge, it works fine whereby it gives me the sizes for each table. But is there another command that will sum up and then give me one size for the whole database?
Please advise if it’s possible.

A trivial modification to the SQL statement provided will sum up the totals for each table and present the overall size. And, it's worth mentioning, Postgres 7.3 is many, many years old, full of nasty bugs. You really, really should upgrade. If you can't, make sure your head is not on the line when it corrupts your data. > > > > > > > > > From: pgsql-admin-owner@postgresql.org > [mailto:pgsql-admin-owner@postgresql.org] On Behalf Of Plugge, Joe R. > Sent: Thursday, March 25, 2010 3:19 PM > To: Khangelani Gama; pgsql-admin@postgresql.org > Subject: Re: [ADMIN] command to check the database size ? > > > > > Execute this against the database that you want to check the size of: > > > > SELECT schemaname, tablename, > > pg_size_pretty(size) AS size_pretty, > > pg_size_pretty(total_size) AS total_size_pretty > > FROM (SELECT *, > > pg_relation_size(schemaname||'.'||tablename) AS size, > > pg_total_relation_size(schemaname||'.'||tablename) AS total_size > > FROM pg_tables) AS TABLES > > WHERE schemaname='public' > > ORDER BY total_size DESC; > > > > > > This will get it by table …. > > > > From: pgsql-admin-owner@postgresql.org > [mailto:pgsql-admin-owner@postgresql.org] On Behalf Of Khangelani Gama > Sent: Thursday, March 25, 2010 7:55 AM > To: pgsql-admin@postgresql.org > Subject: [ADMIN] command to check the database size ? > > > > > Hi > > > > > > Please help, I am new to postgres administration.

I'm pretty sure that the pg_database_size() function did not exist in

Hi
I get the following :
db9879=# SELECT pg_size_pretty(pg_database_size('db9879')) As fulldbsize;
ERROR: Function pg_database_size("unknown") does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
Sorry the previous command gives me the following, I actually ran it in my test server(pg 8.3) when I ran it the first
time:
db9879=# SELECT schemaname, tablename,
db9879-# pg_size_pretty(size) AS size_pretty,
db9879-# pg_size_pretty(total_size) AS total_size_pretty
db9879-# FROM (SELECT *,
db9879(# pg_relation_size(schemaname||'.'||tablename) AS size,
db9879(# pg_total_relation_size(schemaname||'.'||tablename) AS total_size
db9879(# FROM pg_tables) AS TABLES
db9879-# WHERE schemaname='public'
db9879-# ORDER BY total_size DESC;
ERROR: Function pg_relation_size(text) does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
Thanks

Sorry, I overlooked that you were on an ancient version of Postgres ... you really need to migrate to a newer version.

Hi
I get the following :
db9879=# SELECT pg_size_pretty(pg_database_size('db9879')) As fulldbsize;
ERROR: Function pg_database_size("unknown") does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
Sorry the previous command gives me the following, I actually ran it in my test server(pg 8.3) when I ran it the first
time:
db9879=# SELECT schemaname, tablename,
db9879-# pg_size_pretty(size) AS size_pretty,
db9879-# pg_size_pretty(total_size) AS total_size_pretty
db9879-# FROM (SELECT *,
db9879(# pg_relation_size(schemaname||'.'||tablename) AS size,
db9879(# pg_total_relation_size(schemaname||'.'||tablename) AS total_size
db9879(# FROM pg_tables) AS TABLES
db9879-# WHERE schemaname='public'
db9879-# ORDER BY total_size DESC;
ERROR: Function pg_relation_size(text) does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
Thanks

I'm pretty sure that the pg_database_size() function did not exist in
PG 7.3.
