The problem:
1) I create a stupid function like:
CREATE FUNCTION p4() RETURNS integer AS '
BEGIN
FOR i IN 1..1000000 LOOP
insert into info values (random(),random());
END LOOP;
RETURN 1;
END;
' LANGUAGE plpgsql;
2) I create a new db and run "select p4();"
3) I open three connection to the same db and start operation as
"begin work; select p4(); update info set data=RANDOM();commit;"
"create index gino on info(x);"
"begin work; update info set data=RANDOM();"
Well, db schema is nothink more than this:
create table info(meta text, data text, id serial primary key);
4) after a lot of work/insert I've got this:
LOG: recycled transaction log file "00000002000000B0"
LOG: recycled transaction log file "00000002000000B2"
LOG: recycled transaction log file "00000002000000B3"

siae=# ERROR: could not access status of transaction 859388209

I can reproduce this over and over...
The real problem is my configuration: a linux unstable kernel with a debian
unstable branch in a shiny new laptop (with no more test than a memtest86).
Everything else seems working well, of course it doesn't mean it's not my
fault.
Anyway, I write to you asking:
a) do you think it could be a problem of 7.4beta2 (not a problem of mine)?
I remember Tom solved something like this years ago.
b) if so, can you show me next steps to narrow down the problem to give you
a little help?
Thanks a lot for your work,
Andrea Gelmini
