opened connection

Dear List,

I've been using PostgreSQL for quite while, but I'd need some direction on
how to handle an opened socket to the database in longer periods.

I open the connection to my database with PQconnectdb().

I access the database, everything is fine. However, if I don't access the
database for a long time (measured in days), the connection is broken. I
get this error message:

SQL action failed: 'FATAL: terminating connection due to administrator
command SSL connection has been closed unexpectedly.

I tried to check the connection by PQstatus() before calling PQexec(), but
this doesn't detect the broken connection.

How can I detect this problem?

Is it wise to terminate the connection each time the PQexec() finished?
Should I keep the connection for say 1hour, then terminate it?
Is there a common practice?

Any guides are welcome.

Thank you,
Levente
