Hi.
 
I wondering about file size of a table.
 
The table has 43000 pages and in documentation is say's its around 8kb.
It makes it supose to be around 336Mb on disk.
The table is simple just:
org_no varchar (12)
Name varachar(225)
 
But when i create a tablespace on a mfs disk and just loads the data on to the new table (with no index)
The file on the disk increase to more the 500MB and a few seconds later the machine crach.
If i input only 1Milion it's okay but 4 milion is not okay.
 
What does i not understand about tablespaces and the space a 8.0.4 postgresql takes on a frebsd5.4 ?????

Okay i did so, result:
html_slave=# select pg_size_pretty(relation_size('quick_search'));
 pg_size_pretty
----------------
 490 MB
(1 row)
 
html_slave=# select pg_size_pretty(relation_size('html_company'));
 pg_size_pretty
----------------
 1567 MB
(1 row)
 
html_slave=# select pg_size_pretty(database_size('html_slave'));
 pg_size_pretty
----------------
 4120 MB
(1 row)
Okay the quic_search_table is aroun 490, but then i need to ask why does the machine reboot when i only make use of 510MB of the 2.8G mfs disk. .....
 
I need to mail freebsd then.
