PostgreSQL - Several idle connections set bytea_output

Hi guys, i have a situation that i don't know if it is normal, i think not.

I have several idle connections SET bytea_output='escape', so i arrieve to max_connections and have issues with my applicationes, why are there so many connections idle with that query?

Thanks, sorry my english

Are your apps using a connection pool ? If they don't, they should do.
If your app does not use a connection pool, each client opens a new connection to your database. Also check if your are closing your database connection.

Yamil thanks for your reply, i have reviewed my app, and it closes the connections, something for me is not ok, why i have several set bytea_output?, what it means?

bytea is the type for binay data column. In your tables you could have a field which stores binary data.
Altought this message just say the format for those field is the standard 'escape'
If uou are using ADo.NET just add to your connectionstring Pooling=false
