I've employed the following method in one program (it's a CGI which may stay
longer around without using the database connection):

-----
PGconn *conn;

void sig_alrm(int nr)
{
    signal(SIGALRM, SIG_DEF);
    if(conn)
        PQfinish(conn);
    conn = NULL;
}

void use_pgsql(void)
{
    if(!conn) {
        conn = PQconnectdb(...);
        signal(SIGALRM, sig_alrm);
    }
    alarm(60);
}

Before you use any database action now, you call use_pgsql() which will start
the counter and set up the connection.
