Very slow bytea data extraction - Mailing list pgsql-performance

Hi all,
I'm using Postgresql 8.2.3 on a Windows XP system.

I need to
write and retrieve bytea data from a table.
The problem is that, while
data insertion is quite fast, bytea extraction is very slow.
I'm trying
to store a 250KB image into the bytea field.
A simple select query on a
36-row table takes more than one minute to execute.

Any help would be
very appreciated

Thanks in advance

Massimo
