I had deleted a very large number of records out of my SQL table in order to
decrease the harddisk space. But after I use command 'ls -l
/usr/local/pgsql/data/base/', it is found that the size of concerning files
do not reduce due to the effect of 'delete' SQL command. What should I do
if I would like to decrease the harddisk space?
I am looking forward to your response. Thank you very much for any help.
