Re: postgresql.conf

Hola Maria Antonieta
buenas tardes

Dudo mucho que el problema sea postgres Primero ve que el problema no se
trate desde tu aplicacion web asegurate que este cerrando la transacción y
que este cerrando la conexion cuando tu script termine de ejecutarse.

Para ver que procesos te estan generando el problema estos links pueden
ayudarte

https://wiki.duraspace.org/display/DSPACE/Idle+In+Transaction+Problem
http://pg-promotor.blogspot.pe/2010/02/postgres-idle-in-transaction.html

Respecto de tu archivo de configuracion parece que no has tocado nada y
esta todo por defecto aqui tienes una guia rapida para configurar algunos
valores

saludos
