Premysl Maly (premek.maly@seznam.cz) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
Integer overflow in pg_dump
Long Description
Talking about version pg_dump (7.1.3)
Well, it fails, when dumping databases indices (while dumping comment on indexes). I hacked the source code and found
theselect which failed. It is on line 3036 of file pg_dump.
The select looks like:
SELECT description FROM pg_description where oid = 4294958683
it fails always with dtoi4: Integer out of range
I hacked a source, so now the searched oid is qouted:
SELECT description FROM pg_description where oid = '4294958683'
and the bug is gone. Please in a new release look at that. Large numbers should be qouted otherwise they kill SELECT
query.
See you
Premek
Sample Code
in pg_dump source on lines 3036-7 should be:
appendPQExpBuffer(query, "SELECT description FROM pg_description where oid = '");
appendPQExpBuffer(query,oid); appendPQExpBuffer(query,"'");
instead of
appendPQExpBuffer(query, "SELECT description FROM pg_description where oid = ");
appendPQExpBuffer(query,oid);
