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 ?????
 
/Roger
