Well,

Thank for your answer.
I double check what you ask me ...
About the leaking memory, i think as you that i’m having it ...
but i can find where is it or in which part of the procedure is responsable.

The pg_start_activity does not return any uncompleted transation.
I work with subtransations inside the main transaction.

Any ideia ?
