Well, I don't see it happening here. I made up a script consisting of a
whole lot of repetitions of
insert into t1 values(1,2,3);
with one of these inserted every 1000 lines:
\echo 1000 `date`
so I could track the performance. I created a table by hand:
create table t1(f1 int, f2 int, f3 int);
and then started the script with
psql -q -f big.sql testdb
At the beginning I was seeing about two echoes per second. I let it run
for an hour, and I was still seeing about two echoes per second. That's
something close to 170MB of script file read (over 5.7 million rows
inserted by the time I stopped it).
So, either this test case is too simple to expose your problem, or
there's something platform-specific going on. I don't have a windows
machine to try it on ...
