Hi,

Vacuum full is very slow for me . I dont know how to speed it up. It
takes between 60 and 90 minutes.

I have set up autovacuum but I also run vacuum full once per week.

The slowest parts in the vacuum full output are :

INFO:  "a": moved 14076 row versions, truncated 6013 to 1005 pages
DETAIL:  CPU 3.51s/2.16u sec elapsed 1156.00 sec.

INFO:  "b": moved 22174 row versions, truncated 1285 to 933 pages
DETAIL:  CPU 3.77s/1.52u sec elapsed 443.79 sec.

INFO:  "c": moved 36897 row versions, truncated 2824 to 1988 pages
DETAIL:  CPU 3.26s/1.45u sec elapsed 676.18 sec.

How can I speed it up?

Postgres version 8.1.3

Thanks in advance
