I'm new to PG and I'm testing default PG settings
for now.
I have PG 8.1.3. installed with autovacuum=on.
My test table has 15830 records with 190 fields.
I have different fields types (date, numeric, varchar,
integer, smallint,...).
I decided to evaluate PG because I need to use schemas.
First test I did is not very promising.
I tried to update one fields in test table several times
to see how PG react on this.
I do like this:
update table
set field = null
After first execute I get time 3 seconds. Then I repeat
this update. After each update time increase. I get
4 sec, 7 sec, 10 sec, 12 sec, 15 sec, 18 sec, 21 sec.
Is this normal (default) behaviour or I must do something
to prevent this.
