I read the documentation :
http://www.postgresql.org/docs/8.2/interactive/transaction-iso.html#XACT-SERIALIZABLE
and it's maybe my problem
the COPY start a transaction ? if yes each time my trigger select a data
and update then the value returned by the read are the value before the
transaction. It's true ? if yes my question are : also in the same
transaction (like my trigger) ?
Great thanks
Guy
